There are seven months that have 31 days: January, March, May, July, August, October, and December.
This pattern can be remembered using the rhyme: ‘Thirty days hath September, April, June, and November; all the rest have thirty-one, except for February alone, which has twenty-eight days clear, and twenty-nine in each leap year.’ This means that out of the twelve months in a year, a little over half have the maximum number of days. Understanding the distribution of days in each month can be useful for planning events, scheduling activities, and budgeting time effectively.
