Anybody Irish?

On March 17, 2010, the world celebrated St. Patrick's Day.

Among the many celebrations, New York had its parade, Chicago had its green-dyed river and the White House had the Shamrock Ceremony.

Ireland, though, has been celebrating for more than 1,000 years. The holiday celebrates St. Patrick, the patron saint of Ireland, on the anniversary of the day believed to be his death.

Shamrocks, a symbol of Ireland, were believed to be used by St. Patrick to explain the Holy Trinity.

Celebrated during the Christian season of Lent, it is believed that Irish families would traditionally attend mass in the morning, lift the Lenten prohibition against eating meat and celebrate in the afternoon.

Whether Irish or not, many wear green to help celebrate this Irish tradition.
