If October happens to have four Sundays, what day is October 31?


Monday, Sunday



If there are only four Sundays in March, what day of the week can't March 1 be?


It can't be Thursday, Friday, Saturday or Sunday. March has 31 days, which is four weeks and three days. Because there are only four Sundays, 7-3 = 4, March 1 can't be Thursday, Friday or Saturday
