Question

An odd day is one which has both its day and month odd for instance 13:5:2000. How many odd days are there in the year?

Answer 1

Odd months:
January => 31 days => (31-1)/2 + 1 = 16 odd days
March => 31 days => (31-1)/2 + 1 = 16 odd days
May => 31 days => (31-1)/2 + 1 = 16 odd days
July => 31 days => (31-1)/2 + 1 = 16 odd days
September => 30 days => (30)/2 = 15 odd days
November => 30 days => (30)/2 = 15 odd days
16×4 + 15×2 = 64 + 30 = 94 odd days.
