St Patrick’s Day started as a religious celebration of the arrival of Christianity in Ireland in the 17th century. Also called St. Paddy's Day or Paddy's Day or Saint Pats, it celebrates the Roman Catholic feast day of the patron saint of Ireland, St Patrick, and it falls on the same day every year: March 17, the anniversary of St Patrick’s death.
The first ever St Patrick’s Day parade was held in Boston, created by Irish people who immigrated to the US, as a way to connect to their roots after they moved overseas. With the big number of Irish immigrants to the US, the event became bigger and bigger, transforming into a full-blown celebration with Irish (and later non-Irish) people.
Today, St. Paddy’s Day is celebrated in many different countries like UK, Canada, Argentina, Russia, Australia and many others!

St Patrick’s in Australia

This day is not considered a national holiday in Australia, but it is celebrated at Irish pubs across the country. St Patrick Day parades are held in the main cities of Australia, where people hit the streets with Irish or leprechauns costumes or green wigs. It is a fun day and an opportunity to get to know a bit more about the Irish culture.
