Damn that looks good!
You just gotta love the catholic church. If it suits what they need, then it's ok.
From
wiki:
The date of the feast is occasionally moved by church authorities when March 17 falls during Holy Week; this last happened in 1940 when Saint Patrick's Day was observed on 3 April in order to avoid it coinciding with Palm Sunday, and will happen again in 2008, when it shall be held on either March 14 or March 15. After 2008, March 17th will not fall during Holy Week again until 2160.
Damn, 2160 'til the next one!
