March 17th
St. Patrick is Ireland's patron saint. The first St. Patrick's Day paraded was in New York in 1762 that was celebrated from the Irish soldiers that are in the British Army.

Drinking and pinching
Haha yes! :O :D
It is Ireland's national holiday. Where there are Irish people or people of Irish descent, St. Patrick's day will be celebrated. St. Patrick is credited with bringing Christianity to Ireland, which is why he is so important to the Irish people.
Most cities and towns around the country would have parades with all the local football teams and Irish dancers. The biggest is in Dublin City where craic and fun is to be had!
