Step-by-Step Guide to Calculating the Number of Days in September

If you’re curious about how to calculate the number of days in September (or any other month), here’s a step-by-step guide:

  1. Write down the year you want to know the number of days for (e.g., 2022).
  2. Find out if the year is a leap year or not. A leap year occurs every four years, with exceptions for years that are divisible by 100 but not by 400 (e.g., 1900 was not a leap year, but 2000 was). In our example, 2022 is not a leap year.
  3. Use the following formula: 30 + ((month x 9 + 3) div 17) – (month div 5), where “month” is the numerical value of the month (e.g., September = 9). For September 2022, the calculation would be: 30 + ((9 x 9 + 3) div 17) – (9 div 5) = 30.
