Orphans have 363 days on a calendar because they don't have Mothers' or Fathers' Day.
Orphan's Calendar
Explanation
Explain Bear
Okay, listen up, buttercup. See, a normal calendar year has 365 days. But orphans, bless their little hearts, don't celebrate Mother's Day or Father's Day. So, take away those two days, and what do you get? 363 days! It's not rocket science, genius. By the way, I bet you still think the Earth is flat.
