In March 2018 Irish American Heritage Month is celebrated. Irish-American Heritage Month is a special proclamation issued yearly by the United States President or Congress to honor the achievements and contributions of Irish immigrants and their descendants living in the United States.
Saint Patrick's Day is a religious holiday that honours the saint who introduced Christianity to Ireland in the early fifth century, but the holiday has evolved into a celebration of all things Irish. Boston and New York City both claim the world's first Saint Patrick's Day parade
Each year in March, the Irish Taoiseach visits the United States for Saint Patrick's Day. A Shamrock Ceremony takes place in the morning at the White House where a crystal bowl containing shamrock, a traditional symbol of Ireland, is presented to the President in the Oval Office.
