The countdown above shows the exact time remaining until March 17th. Whether you are planning a parade outing, organizing a celebration, or just looking forward to wearing green, this countdown keeps you on track.
St. Patrick's Day has evolved from a religious feast day in Ireland to a global celebration of Irish culture, with parades, green beer, traditional music, and festivities in cities around the world. Chicago famously dyes its river green, and New York City hosts the largest St. Patrick's Day parade, with over 150,000 marchers.
About St. Patrick's Day
Saint Patrick was born in Roman Britain around 385 AD and was kidnapped at age 16 by Irish raiders who took him to Ireland as a slave. After six years, he escaped, studied religion, and returned to Ireland as a missionary. He is credited with bringing Christianity to Ireland and using the shamrock to explain the concept of the Holy Trinity.
The first St. Patrick's Day parade was not held in Ireland but in New York City in 1762, organized by Irish soldiers serving in the British Army. The holiday remained primarily a religious observance in Ireland until the 1970s, when it began evolving into the multi-day cultural festival it is today. The Irish government now uses the week around March 17th to showcase Irish culture globally.
Today, approximately 33 million Americans claim Irish ancestry, more than six times the population of Ireland itself. St. Patrick's Day is celebrated with parades in cities from Dublin to Sydney, and landmarks worldwide are illuminated in green as part of Tourism Ireland's "Global Greening" initiative.

Why do people wear green on St. Patrick's Day?
Wearing green on St. Patrick's Day is tied to Irish nationalism and the 'wearing of the green' tradition. Interestingly, the original color associated with St. Patrick was blue. Green became dominant in the 19th century, linked to the Irish flag, the shamrock (which St. Patrick used to explain the Holy Trinity), and the lush green landscape of Ireland.
