St. Patrick's Day is celebrated on March 17th to honor St. Patrick, the patron saint of Ireland who brought Christianity to the country. St. Patrick was born in Wales but captured and brought to Ireland as a slave at a young age, where he found faith in God and prayed every night. After escaping to France and becoming a priest, Patrick returned to Ireland and used the shamrock to explain the Holy Trinity, converting many to Christianity. He spent 60 years traveling Ireland spreading the word of God before dying on March 17th, 493 AD.
