What month has thirty days?
There is a good little rhyme to remember this:
30 Days has September, April, June and November. All the rest
have 31 excepting February alone which has 28 and in a leap year
Thirty days hath September, April, June and November;
February has twenty eight alone
All the rest have thirty-one
Except in Leap Year, that's the time
When February's Days are twenty-nine
All of them, except February!
