Here’s how you know with months have 31 days
Apparently, you don’t need a calendar as long as you have two hands. This trick helps you know how many days each month has without looking at an actual calendar to check. Read the following instructions carefully since you will have to memorize the steps to have your own knuckle calendar.
Tap each of your knuckles and the wells in between while reciting the months of the year. You’ll start with the pinky knuckle and work your way to the other side. When you get to the last knuckle, go to the other hand’s knuckle, and continue reciting. Your knuckles represent the months with 31 days. Get it? Higher up means a higher number of days. The wells between your knuckles represent the months with 30 days. Remember that February only has 28 days (or 29 in a leap year). It’s easier than it sounds. You should try it!
