Why celebrate Saint Patrick's Day?

Answer 1

we celebrate saint patricks day because he brought the cathlic religon to Ireland and explaned the religon through using a clover/shamrock we also celebrate it because he is said to have gotten all the snakes out of Ireland aswell...

When he was about 16 he was captured from Britain by Irish raiders and taken as a slave to Ireland, where he lived for six years before escaping and returning to his family. After entering the Church, he returned to Ireland as an ordained bishop in the north and west of the island, but little is known about the places where he worked.

By the eighth century he had come to be revered as the patron saint of Ireland. The Irish monastery system evolved after the time of Patrick and the Irish church did not develop the diocesan model that Patrick and the other early missionaries had tried to establish.Patrick with teaching the Irish about the concept of the trinity by showing people the shamrock, a 3-leaved clover, using it to highlight the Christian belief of 'three divine persons in the one God'
