One of my Guinness t-shirts is wrong this year. Since St Patrick's Day was moved by 2 days the one I wear on March 17th has the wrong date on it.

This year, for one year only, it's on the March 15th instead of the 17th, so it doesn't clash with the start of Holy Week leading up to Easter. I've got my cans of Guinness in the fridge ready to open tonight.
