St. Patrick's Day is coming up on March 17. But why do we celebrate the Irish holiday? Here's what to know, plus food deals you can snag in Arizona

St. Patrick's Day is the feast day for St. Patrick, the patron saint of Ireland. Irish citizens celebrate the day by attending church to honor the saint who brought Christianity to Ireland in the 5th century. It's celebrated on March 17 annually to honor St. Patrick's death date.

It seems like everyone, deep down, wants to have some kind of connection to Ireland. Even if it’s through your best friend’s cousin’s neighbor’s cat, who once chased a leprechaun in Dublin, it's close enough.
