A month can contain 5 Sundays, 5 Mondays, and 5 Tuesdays only if it has at least 29 days. This situation occurs in months with 31 days when the month starts on a Sunday, Monday, or Tuesday. Therefore, it can happen once or twice a year, depending on the calendar configuration.

December can have five Sundays, Mondays, and Tuesdays only in specific years. This occurs when December 1st falls on a Sunday, making the Sundays fall on the 1st, 8th, 15th, 22nd, and 29th, while Mondays and Tuesdays also align to allow for five occurrences. This scenario happens approximately once every 28 years in the Gregorian calendar, with the next occurrence in 2030.
