190 views

The probability that an ordinary year has 53 Sundays and 53 Mondays is 0. An ordinary year has 365 days, corresponding to 52 weeks and 1 extra day. This extra day can be any of the seven days of the week (Sunday through Saturday), but a year cannot have two extra days, so it’s impossible to have 53 Sundays and 53 Mondays in the same ordinary year.

FAQs & Answers

  1. How many Sundays are in an ordinary year? An ordinary year with 365 days has 52 Sundays and one extra day, so it can have either 52 or 53 Sundays depending on which weekday the year starts.
  2. Can a leap year have 53 Sundays and 53 Mondays? Yes, a leap year has 366 days with two extra days, so it is possible for a leap year to have both 53 Sundays and 53 Mondays.
  3. Why can't an ordinary year have 53 Sundays and 53 Mondays? Because an ordinary year has only one extra day beyond 52 weeks, there is not enough days to have 53 occurrences of two different weekdays.
