DUBLIN (AP) - Landmark buildings across Ireland and the world have been floodlit green for St. Patrick's Day as global celebrations of the Emerald Isle's patron saint are culminating in parades and celebrations in Dublin, New York and scores of other cities Tuesday.
Here are St. Patrick's Day events happening worldwide:
UNITED STATES
Home to more than 40 million citizens with Irish blood, St. Patrick's Day is arguably a bigger event in some American cities than even in Ireland. But because this year's holiday falls on a Tuesday, most U.S. towns and cities held their festivities early on the weekend.
Not so for the flagship parade up Fifth Avenue in New York, nor diplomatic events in Washington, where President Barack Obama and the Republican-led Congress take turns toasting their Irish guests at separate events.
New York's parade stepped off with a jovial Cardinal Timothy Dolan as grand marshal.
"I'm as radiant as the sun, so thanks be to God for the honor and the joy," said the archbishop of the Roman Catholic Archdiocese of New York.
The parade included the first gay contingent marching under its own banner, a group representing gay employees of the broadcaster NBC, a major parade sponsor.
In protest of parade organizers' policy on LGBT groups, Mayor Bill de Blasio did not march.
Also, in Washington, for the first time, the leaders of Northern Ireland's power-sharing government aren't coming. Obama encouraged them to stay in Belfast, where rival British Protestant and Irish Catholic leaders are negotiating to keep their 8-year-old coalition from unraveling over a bitter budget dispute.
IRELAND
President Michael Higgins attended Mass at St. Mary's Pro-Cathedral in Dublin, where Catholic Archbishop Diarmuid Martin blessed sprigs of shamrock in the traditional start to Ireland's national holiday.
Hundreds of thousands of Dubliners and tourists lined the nearby route of the Dublin parade, the culmination of a four-day festival featuring music and dance performances, pub crawls, cultural tours and street arcades. Face-painted dancers, eccentrically-themed floats and U.S. marching bands snaked their way down O'Connell Street across the River Liffey to St. Patrick's Cathedral a mile away.
A man dressed as St. Patrick - but donning sunglasses and dispensing smart-aleck comments to the crowd, along with playful thumps from his club-like crozier - led the way.
Later Tuesday, Irish Prime Minister Enda Kenny is guest of honor at the White House following weekend visits to Georgia and Texas. Almost his entire Cabinet has spent the past week traveling worldwide promoting Ireland's tourism, culture and strong rebound from a crippling 2008 banking crisis.
BRITAIN
At a barracks in Aldershot, England, Prince William and his pregnant wife, Kate, presented shamrocks to soldiers from the Irish Guards, one of the two Irish-recruited regiments in the British Army.
Kate, 33, handed out baskets of shamrocks and pinned a sprig on the collar of the regiment's mascot, an Irish wolfhound called Domhnall. The 3-year-old dog was treated to a sip of Guinness at the ceremony's end.
