Days in a month without weekends

The number of days in a month excluding weekends will depend on the specific month and year. On average, there are 22 weekdays in a month, and this number can vary from 21 to 23 depending on the number of days in the month and the day of the week on which it starts. Also the number of working days in a month depends on the specific holidays for each month and the holiday calendar of each specific country.

How many days are there in a month on average

Days of the month with knuckles

One way to remember the number of days in each month using your knuckles is by following these steps:

  1. Make a fist with your left hand and extend your fingers.
  2. Start counting with January on your left-most knuckle (the one on the far left of your index finger).
  3. Count the months on your knuckles and the spaces between your knuckles. Each knuckle represents a month with 31 days, while the space between the knuckles represents a month with 30 days.
  4. When you reach July, which falls on the last knuckle of your index finger, go back to the first finger while you keep counting each of the months, so now the first finger will correlate with the month of august.
  5. February, which has 28 days (or 29 in a leap year), is represented by the space after the knuckle of your little finger.
