Today is Israel's 63rd anniversary of Independence Day, also known as Yom Ha'atzmaut (יום העצמאות) and Google Israel has a special logo to celebrate.
The logo leads to a search result for [יום העצמאות] and the first results goes to the Hebrew version of the Yom Ha'atzmaut Wiki Page.
The holiday is celebrated every year on the 5th of the Jewish month of Iyar. It was in 1948 when Israel was declared a state.
