Why February has 28 or 29 days?


Which month has 28 days?

Most people would answer “February.” However, all twelve months have 28 days. The other months have 30 and 31 days. That certainly means all months have 28 days

According to Wikipedia, February is the second month of the year on the Julian and Gregorian calendars. It is the shortest month and the only month with fewer than 30 days. The month has 28 days in common years and 29 days in leap years.

Interesting things about February

  • In the Southern Hemisphere, February is the seasonal equivalent of August in the Northern Hemisphere.
  • February starts on the same day of the week as March and November in common years, and on the same day of the week as August in leap years.
  • February ends on the same day of the week as October every year and January in common years only. In leap years, it is the only month that ends on the same weekday it begins.
  • February was named after the Latin term februum, which means purification, via the purification ritual Februa held on February 15 (full moon) in the old lunar Roman calendar.
  • January and February were the last two months to be added to the Roman calendar, since the Romans originally considered winter a monthless period.
  • Many people mispronounce February. They pronounce the ‘ru’ of “February” you rather than /ruː/ roo, as if it were spelled “Feb-u-ary”. This comes about by analogy with “January” (which ends in “-uary” but not “-ruary”).
  • Having only 28 days in common years, it is the only month of the year that can pass without a single full moon.
  • It is also the only month of the calendar that once every six years and twice every 11 years, will have only four full 7-day weeks where the first day of the month starts on a Monday and the last day ends on a Sunday.
