Why is Facebook blue ?

Facebook is blue because Zuckerberg is colour-blind.


According to The New Yorker, the reason is simple. It’s because Mark Zuckerberg is red-green colourblind. This means that blue is the colour Mark can see the best. In his own words Zuck says:

“Blue is the richest color for me; I can see all of blue.”

Yes, Mark is red-green colorblind, so blue is the easiest color for him to see. Additionally, Facebook has always been pretty monochromatic since from the beginning he has wanted the site to remain as simple as possible.

The anniversary is known as “World Peace and Understanding Day.” Paul P. Harris, an attorney, wanted to create a professional group with the same friendly spirit he felt in the small towns of his youth. They decided to call the new club “Rotary” after the practice of rotating meeting locations.

The name Rotary International was adopted in 1922.

Rotary International Rotary International is an international service organization whose stated purpose is to bring together business and professional leaders in order to provide humanitarian services, encourage high ethical standards in all vocations, and help build goodwill and peace in the world.

World Scout Day - February 22

Scouts' Day or Guides' Day is a generic term for special days observed by members of the Scouting movement throughout the year. Some of these days have religious significance, while others may be a simple celebration of Scouting. Typically, it is a day when all members of Scouting will re-affirm the Scout Promise.
Worldwide in nearly all Scout associations, Founders' Day is celebrated on 22 February, the birthday of Robert Baden-Powell, 1st Baron Baden-Powell (born in 1857), the founder of Scouting, and coincidentally also of his wife Olave Baden-Powell (born in 1889).
Individual associations also celebrate their own founding on other dates, although these are generally restricted to "major" anniversaries, such as a decennialGirl Scouts of the USA celebrate Founders Day on 31 October, the birthday of Juliette Low.
Thinking Day is celebrated on 22 February. The World Association of Girl Guides and Girl Scouts (WAGGGS) chose the date as it was the birthday of Scouting and Guiding founder Robert Baden-Powell and of Olave Baden-Powell. It is thus celebrated by Girl Guides and Girl Scouts associations. SAGNOs (those associations which are part simultaneously of WAGGGS and WOSM) usually take part in it. It is also celebrated by some boy-oriented scout associations belonging to WOSM (i.e. Greece, where it is calledImera Skepseos),

International Mother Language Day - February 21

International Mother Language Day (IMLD) (Bengaliআন্তর্জাতিক মাতৃভাষা দিবস Antôrjatik Matribhasha Dibôs) is a worldwide annual observance held on 21 February to promote awareness of linguistic and cultural diversity and multilingualism. First announced by UNESCO on 17 November 1999, it was formally recognized by the United Nations General Assembly in its resolution establishing 2008 as the International Year of Languages.
International Mother Language Day has been being observed since 2000[4] to promote peace and multilingualism. The date corresponds to the day in 1952 when students from the University of DhakaJagannath University and Dhaka Medical College, demonstrating for the recognition of Bengali as one of the two national languages of East Pakistan, were shot dead by police near the Dhaka High Court in the capital of present-day Bangladesh.
"Mother language" is the calque of a term used in several Romance languages — lengua materna (Spanish), lingua madre (Italian) and langue maternelle (French) — as well as the Sanskrit matribhasha and Tamil "thaimozhi". The more literal and more common English translation is "mother tongue", while "native language" has the same meaning and is also in common use. In linguistics, the English term "mother language" usually refers to an ancestral language, often a proto-language, relative to its descendent language family.
International Mother Language Day was proclaimed by the General Conference of the United Nations Educational, Scientific and Cultural Organization (UNESCO) in November 1999 (30C/62). On 16 May 2009 the United Nations General Assembly, in its resolution A/RES/61/266, called on its member states "to promote the preservation and protection of all languages used by people of the world".[5]In the resolution, the General Assembly proclaimed 2008 as the International Year of Languages to promote unity in diversity and international understanding through multilingualism and multiculturalism. The resolution was suggested by Rafiqul Islam,a Bengali living in Vancouver, Canada. He wrote a letter to Mr. Kofi Anan on 9 January 1998 asking him to take a step for saving all the languages of the world from the possibility of extinction and to declare an International Mother Language Day. Rafiq proposed the date as 21 February on the pretext of 1952 killing in Dhaka on the occasion of Language Movement.
Languages are the most powerful instruments of preserving and developing our tangible and intangible heritage. All moves to promote the dissemination of mother tongues will serve not only to encourage linguistic diversity and multilingual education but also to develop fuller awareness of linguistic and cultural traditions throughout the world and to inspire solidarity based on understanding, tolerance and dialogue.

World Day of Social Justice - February 20

World Day of Social Justice is a day recognizing the need to promote efforts to tackle issues such as povertyexclusion and unemployment. Many organizations, including the UN and the International Labour Office, make statements on the importance of social justice for people. Many organizations also present plans for greater social justice by tackling poverty, social and economic exclusion and unemployment. The United Nations General Assembly has decided to observe 20 February annually, approved on 26 November 2007 and starting in 2009, as the World Day of Social Justice.[1]
As recognized by the World Summit, social development aims at social justice, solidarity, harmony and equality within and among countries and social justice, equality and equityconstitute the fundamental values of all societies. To achieve “a society for all” governments made a commitment to the creation of a framework for action to promote social justice at national, regional and international levels. They also pledged to promote the equitable distribution of income and greater access to resources through equity and equality and opportunity for all. The governments recognized as well that economic growth should promote equity and social justice and that “a society for all” must be based on social justice and respect for all human rights and fundamental freedoms.Social justice is an underlying principle for peaceful and prosperous coexistence within and among nations. We uphold the principles of social justice when we promote gender equality or the rights of indigenous peoples and migrants. We advance social justice when we remove barriers that people face because of gender, age, raceethnicityreligionculture or disability.
For the United Nations, the pursuit of social justice for all is at the core of our global mission to promote development and human dignity. The adoption by the International Labour Organization of the Declaration on Social Justice for a Fair Globalization is just one recent example of the UN system’s commitment to social justice. The Declaration focuses on guaranteeing fair outcomes for all through employment, social protection, social dialogue, and fundamental principles and rights at work.
The General Assembly proclaimed 20 February as World Day of Social Justice in 2007, inviting Member States to devote the day to promoting national activities in accordance with the objectives and goals of the World Summit for Social Development and the twenty-fourth session of the General Assembly. Observance of World Day of Social Justice should support efforts of the international community in poverty eradication, the promotion of full employment and decent work, gender equity and access to social well-being and justice for all.

Valentine’s Day - February 14

Valentine's Day, also called Saint Valentine's Day or the Feast of Saint Valentine, is an annual holiday celebrated on February 14. It originated as a Western Christian liturgical feast day honoring one or more early saints named Valentinus, and is recognized as a significant cultural and commercial celebration in many regions around the world, although it is not a public holiday in any country.
Several martyrdom stories associated with the various Valentines that were connected to February 14 were added to latermartyrologies, including a popular hagiographical account of Saint Valentine of Rome which indicated he was imprisoned for performing weddings for soldiers who were forbidden to marry and for ministering to Christians, who were persecuted under the Roman Empire. According to legend, during his imprisonment, Saint Valentine healed the daughter of his jailer, Asterius, and before his execution, he wrote her a letter signed "Your Valentine" as a farewell.
The day first became associated with romantic love within the circle of Geoffrey Chaucer in the 14th century, when the tradition ofcourtly love flourished. In 18th-century England, it evolved into an occasion in which lovers expressed their love for each other by presenting flowers, offering confectionery, and sending greeting cards (known as "valentines"). In Europe, Saint Valentine's Keysare given to lovers "as a romantic symbol and an invitation to unlock the giver’s heart", as well as to children, in order to ward offepilepsy (called Saint Valentine's Malady). Valentine's Day symbols that are used today include the heart-shaped outline, doves, and the figure of the winged Cupid. Since the 19th century, handwritten valentines have given way to mass-produced greeting cards.
Saint Valentine's Day is an official feast day in the Anglican Communion, as well as in the Lutheran Church. Many parts of theEastern Orthodox Church also celebrate Saint Valentine's Day, albeit on July 6 and July 30, the former date in honor of the Romanpresbyter Saint Valentine, and the latter date in honor of Hieromartyr Valentine, the Bishop of Interamna (modern Terni).

World Radio Day - February 13

World Radio Day is an observance day held annually on 13 February. World Radio Day is about celebrating radio, why we love it and why we need it today more than ever. A day to remember the unique power of radio to touch lives and bring people together across every corner of the globe. It was proclaimed on 3 November 2011 by UNESCO's 36th General Conference after originally proposed by the Kingdom of Spain.
Following a request from the Spanish Radio Academy, on 20 September 2010 Spain proposed that the UNESCO Executive Board include an agenda item on the proclamation of a World Radio Day. UNESCO's Executive Board approved the agenda item in its provisional agenda, for the proclamation of a "World Radio Day" on 29 September 2011. UNESCO carried out a wide consultation in 2011 with diverse stakeholders, i.e. broadcasting associations; public, state, private, community and international broadcasters; UN agencies; funds and programmes; topic-related NGOs; academia; foundations and bilateral development agencies; as well as UNESCO Permanent Delegations and National Commissions for UNESCO. Among the answers, 91% were in favour of the project, including official support from the Arab States Broadcasting Union (ASBU), the Asia-Pacific Broadcasting Union (ABU), the African Union of Broadcasting (AUB), the Caribbean Broadcasting Union (CBU), the European Broadcasting Union (EBU), the International Association of Broadcasting (IAB), the North American Broadcasters Association (NABA), the Organización de Telecomunicaciones Ibeoramericanas (OTI), BBC, URTI, Vatican Radio, etc. The results of this consultation are available in UNESCO's document 187 EX/13.
The Board recommended to the UNESCO 36th session of the General Conference that it proclaim a World Radio Day at its 36th session, and that this day be celebrated by UNESCO on 13 February, the anniversary of the day the United Nations established United Nations Radio in 1946. It also invited all United Nations Member States, organizations of the United Nations system and other international and regional organizations, professional associations and broadcasting unions, as well as civil society, including non-governmental organizations and individuals, to duly celebrate World Radio Day, in the way that each considers most adequate. The Board further requested that UNESCO's Director-General brought the resolution to the attention of the Secretary-General of the United Nations so that World Radio Day could be endorsed by the General Assembly and celebrated by the whole system. The matter was subsequently treated by UNESCO's General Conference, which adopted resolution contained in the file 36 C/63. World Radio Day was thus unanimously proclaimed by all Member States of UNESCO in November 2011.
In December 2012, The General Assembly of the UN endorsed the proclamation of World Radio Day, thereby becoming a Day to be celebrated by all UN agencies, funds and programmes and their partners. File A/RES/67/124. Various radio industry bodies around the world are supporting the initiative by encouraging stations in developed countries to assist those in the developing world. At UNESCO the consultation, proclamation and celebrations were handled by Mirta Lourenco, Chief of the Sector for Media Development.

World Day of the Sick - February 12

The World Day of the Sick is a feast day of the Roman Catholic Church which was instituted on May 13, 1992 by Pope John Paul II. Beginning on February 11, 1993, it is celebrated every year on the commemoration of Our Lady of Lourdes, for all believers seeks to be "a special time of prayer and sharing, of offering one's suffering".
Pope John Paul II had been diagnosed with Parkinson's disease as early as 1991, an illness which was only disclosed later, and it is significant that he decided to create a World Day of the Sick only one year after his diagnosis.[3] The Pope had written a great deal on the topic of suffering and believed that it was very much a salvific and redeeming process through Christ, as he indicated in his apostolic letter Salvifici Doloris.
The feast of Lourdes was chosen because many pilgrims and visitors to Lourdes have reportedly been healed by intercessions of the Blessed Virgin. The pontiff was also fond of the sanctuary of Harissa in Lebanon.
In 2005, the World Day of the Sick had a special significance since it was the year John Paul died from a sepsis. Many people had gathered around him as he lay dying.
In 2013, Pope Benedict XVI announced his resignation during this feast day, and he cited his declining health as his reason for retiring.

Darwin Day - February 12

Darwin Day is a celebration to commemorate the anniversary of the birth of Charles Darwin on 12 February 1809. The day is used to highlight Darwin's contribution to science and to promote science in general. Darwin Day is celebrated around the world.
The celebration of Darwin's work and tributes to his life have been organized sporadically since his death on 19 April 1882, at age 73. Events took place at Down House, in Downe on the southern outskirts of London where Darwin and members of his family lived from 1842 until the death of his wife, Emma Darwin, in 1896.
In 1909, more than 400 scientists and dignitaries from 167 countries met in Cambridge to honour Darwin's contributions and to discuss vigorously the recent discoveries and related theories contesting for acceptance. This was a widely reported event of public interest. Also in 1909, on 12 February, the 100th birth anniversary of Darwin and the 50th anniversary of the publication of On The Origin of Species were celebrated by the New York Academy of Sciences at the American Museum of Natural History. A bronze bust of Darwin was unveiled. On 2 June 1909 the Royal Society of New Zealand held a "Darwin Celebration". "There was a very large attendance."
On 24–28 November 1959, The University of Chicago held a major, well publicised, celebration of Darwin and the publication of On the Origin of Species, the largest event of the Darwin Centennial Celebration.
Scientists and academics sometimes celebrated 12 February with "Phylum Feast" events—a meal with foods from as many different phyla as they could manage, at least as early as 1972, 1974, and 1989 in Canada.
In the United States, Salem State College in Massachusetts has held a "Darwin Festival" annually since 1980, and in 2005, registered "Darwin Festival" as a service mark with the US Patent and Trademark Office.
The Humanist Community of Palo Alto, California, was motivated by Dr. Robert Stephens in late 1993 to begin planning for an annual "Darwin Day" celebration. Its first public Darwin Day event was a lecture by Dr. Donald Johanson (discoverer of the early hominid "Lucy"), sponsored by the Stanford Humanists student group and the Humanist Community on 22 April 1995. The Humanist Community continues its annual celebration of Darwin, science, and humanity, on 12 February.
Independently, in 1997, Professor Massimo Pigliucci initiated an annual "Darwin Day" event with students and colleagues at the University of Tennessee. The event included several public lectures and activities as well as a teachers' workshop meant to help elementary and secondary school teachers better understand evolution and how to communicate it to their students, as well as how to deal with the pressures often placed on them by the creationism movement.
In 2015, Delaware's governor Jack Markell declared February 12 “Charles Darwin Day”, making Delaware the first state in America to formally mark the occasion.
House Resolution 67, introduced by Representative Jim Hines in the United States House of Representatives on February 2, 2015 would designate February 12 as Darwin Day in the United States. It would recognize Darwin as "a worthy symbol on which to focus...a global celebration of science and humanity."

International Day of Women and Girls in Science - February 11

Gender equality has always been a core issue for the United Nations. Gender equality and the empowerment of women and girls will make a crucial contribution not only to economic development of the world, but to progress across all the goals and targets of the 2030 Agenda for Sustainable Development as well.
On 14 March 2011, the Commission on the Status of Women adopted a report at its fifty-fifth session, with agreed conclusions on access and participation of women and girls in education, training and science and technology, and for the promotion of women’s equal access to full employment and decent work. On 20 December 2013, the General Assembly adopted a resolution on science, technology and innovation for development, in which it recognized that full and equal access to and participation in science, technology and innovation for women and girls of all ages is imperative for achieving gender equality and the empowerment of women and girls.
On 15 December 2015, the General Assembly adopted the resolution, deciding to proclaim 11 February of each year of the International Day of Women and Girls in Science. The United Nations invites all Member States, all organizations and bodies of the United Nations system and other international and regional organizations, the private sector and academia, as well as civil society, including non-governmental organizations and individuals, to observe the International Day of Women and Girls in Science in an appropriate manner, including through education and public awareness-raising activities, in order to promote the full and equal participation of women and girls in education, training, employment and decision-making processes in the sciences, eliminate all discrimination against women, including in the field of education and employment, and overcome legal, economic, social and cultural barriers thereto by, inter alia, encouraging the development of science education policies and programming, including school curricula, as appropriate, to encourage greater participation of women and girls, promote career development for women in science and recognize the achievements of women in science.

International Day of Zero Tolerance to Female Genital Mutilation - February 6

International Day of Zero Tolerance to Female Genital Mutilation is a UN-sponsored awareness day that takes place February 6 each year.
It is an effort to make the world aware of female genital mutilation (also called FGM) and to promote its eradication. The World Health Organization has said that "Though the practice has persisted for over a thousand years, programmatic evidence suggests that FGM/C can end in one generation."
First, on February 6, 2003, Stella Obasanjo, the First Lady of Nigeria and spokesperson for the Campaign Against Female Genital Mutilation, made the official declaration on "Zero Tolerance to FGM" in Africa during a conference organized by the Inter-African Committee on Traditional Practices Affecting the Health of Women and Children (IAC). Then the UN Sub-Commission on Human Rights adopted this day as an international awareness day.
In 2014, 17-year-old Bristol student Fahma Mohamed created an online petition with Change.org on the International Day of Zero Tolerance to Female Genital Mutilation, askingMichael Gove, then the education secretary in the United Kingdom, to write to the leaders of all primary and secondary schools in the United Kingdom, encouraging them to be alert to the dangers of FGM. The petition attained more than 230,000 supporters and was one of the fastest growing UK petitions on Change.org. Michael Gove met with Fahma Mohamed and members of the youth group Integrate Bristol, who have also played a key role in raising awareness of FGM. He also sent a letter to all headteachers in England informing them of new guidelines on children's safety, including guidance on FGM. These new guidelines marked the first time the safeguarding guidelines included specific mention of FGM and encouraged teachers to be vigilant against it.
