Saint Patrick's Day (Irish: Lá Fhéile Pádraig, "the Day of the Festival of Patrick") is a cultural and religious holiday celebrated on 17 March. It commemorates Saint Patrick (c. AD 387–461), the most commonly recognised of the patron saints of Ireland, and the arrival of Christianity in Ireland.It is observed by the Catholic Church, the Anglican Communion (especially the Church of Ireland),the Eastern Orthodox Church and Lutheran Church. Saint Patrick's Day was made an official feast day in the early seventeenth century, and has gradually become a celebration of Irish culture in general.
The day is generally characterised by the attendance of church services, wearing of green attire and the lifting of Lenten restrictions on eating, and drinking alcohol, which is often proscribed during the rest of the season.
But this is not all... St Patrick's Day falls on Thu 17th March, but events are running all week.
The parade starts in Green Park at 12 noon (18th March) and continues through Central London and Trafalgar Square, dispersing at Whitehall Palace. Events across London take place throughout the preceding week.
The Mayor’s St Patrick’s Day Parade and Festival will take place on Sunday 18 March 2012.
Set to be one of London's liveliest celebrations of the year, over 100,000 people attended last year's event.
The parade, featuring a colourful array of floats, marching bands and groups representing the Irish Counties, will proceed through central London from Green Park to Trafalgar Square starting at 12 noon.

This fantastic, free family day out is a great way to experience all things Irish from food and dance to crafts, culture, music and much more.
This is always a great, good-humoured and fun day out for all the family.
