(CNN) — March is a grand time of year when you're Irish. Or when you're of Irish heritage. Or when you wish you were of Irish heritage. Or when you just claim you're Irish even though you're not.

St. Patrick's Day, which is on Tuesday, March 17, in 2020 easily draws out the Irish in plenty of people all over the world.

And one of the best ways we celebrate this is with parades -- boisterous, green-colored, shamrock-festooned, music-blaring parades.

This year, some parades have been canceled to stem the spread of coronavirus, so check parade sites and local news before you pack up to attend.

What follows are 14 of the best St. Patrick's Day parades in destinations around the world, along with a short history of the saint himself and the holiday first.

So who was St. Patrick anyway?

Patrick was born in 385 A.D ., back when Ireland was still pagan territory. When he was 16, the British-born Patrick was brought to Ireland as a slave. He escaped six years later and became a priest.

He eventually returned to the island and started converting the natives to Christianity. He's the patron saint of Ireland and as such is invoked to protect the spiritual and worldly interests of the island and its people.

He died in 461 A.D.

How is the day celebrated?

St. Patrick's Day is a national holiday in Ireland . That means banks, stores and businesses close for the day. The holiday has stronger religious overtones in this strongly Catholic country.

The US Census says roughly 32.6 million US residents claimed Irish ancestry in 2017. This is more than six times the population of Ireland (about 5 million). It's more of a secular event and a party in the United States, and plenty of non-Catholics join in.

The first St. Patrick's Day celebration in the United States was held in Boston in 1737. And it's just grown from there.

Enough background. Let's get to those parades! Click the link in each city for details:
