Did you know that no feast day of the Church can fall in Holy Week ?
Easter's very early this year, and two feast days fall in that week - St Patrick on the 17th and St Joseph on the 19th.
So Paddy's been moved back to this Friday, the 14th, and St Joseph to the 15th.
And as all racegoers know, where St Patrick goes, the Cheltenham Drinking Festival is sure to follow.
(This annual drinking festival also features some kind of horse-racing, traditionally watched in an on-course bar over a sea of heads).
