Today isn't just Billy's birthday, Shakespeare's birthday (and the day of his death), and St George's Day, it's an important national holiday in Turkey.
The following is taken verbatim from Todays Zaman (so make allowances for their translation)
April 23 National Sovereignty and Children's Day, which marks the foundation of the Turkish Parliament in 1920, is being celebrated with a series of events throughout Turkey and Turkish Republic of Northern Cyprus on Friday.
State officials headed by Parliament Speaker Mehmet Ali Şahin paid a visit to Anıtkabir, modern Turkey's founder Mustafa Kemal Atatürk's Mausoleum.
High-level state officials observed a minute of silent and sung the National Anthem.
Later Şahin signed the Anıtkabir Special Register and wrote: "The Turkish parliament, which has been working to reach the level of contemporary civilizations, will keep working with a great determination in accordance with your (Ataturk's) principles."
Groups of children from different schools are putting out their massive shows at the May 19 Stadium in Ankara.
Students, scouts and folklore dancers made a ceremonial march in the beginning of celebrations in the stadium.
April 23 is the only children's festival in the world.
It was on April 23, 1920, during the War of Independence, that the Grand National Assembly was inaugurated in Ankara and Mustafa Kemal Atatürk laid down the foundations of a new, independent, secular, and modern Republic of Turkey.
He also dedicated this day to the children of the country to emphasize that they are the future of the new nation and since then, April 23 National Sovereignty and Children's Day is celebrated in Turkey as a national day. The importance of April 23 as a special day of children has also been recognized internationally and United Nations Children's Fund (UNICEF) endorsed this important day as the International Children's Day.
Every year on this date, children from all around the world come together in Turkey to enjoy Children's Day celebrations and festivities in a hope that these memories of friendly atmosphere will contribute to a future of enhanced brotherhood and peace among nations.
