Did you know that you are able to calculate which day a specific date falls on? In planning or preparing for specific events, what we always need to know is which day it falls on. For that, we look it up on the nearest calendar or look it up on our phones. Now, you don’t have to do this anymore – you can simply calculate it yourself!  Like Christmas eve, somebody’s birthday, an important meeting or other things you want to keep track on. The best thing is that it is simple! Let me teach you how to do it:


There is a pattern in the calendar from which you can calculate which day any specific date falls on. First thing:
Every month has its own numeric value, and they are:

  • January is 6
  • February is 2
  • March is 2
  • April is 5
  • May is 0
  • June is 3
  • July is 5
  • August is 1
  • September is 4
  • October is 6
  • November is 2
  • December is 4

These numeric values are for the year 2017. You can also use this same calculation for 2018 and 2019, but you have to add 1 in value to each of the month for every year. However, for 2020 we’ll have to recalculate the values because it is a leap-year.
Also, every day of the week has a value. This is always the same and it starts with Sunday being 0, and Monday 1, Tuesday 2, Wednesday 3 and so forth.

Here is what you do:
Pick a date, for example July 4th. Now, let’s first take the month: July is a 5. Then we add these two and we get 9. Then you have to divide your answer by 7 (you are then taking out the weeks) In this example that would be only one time, so 1. And then you the remainder of 2, which is the second day of the week – which is a TUESDAY .

Take Christmas eve, 24th of December: December is a 4 + the date which is 24 gives you 28. Dividing this by 7 gives you 4 which 0 remaining in value.This means that Christmas EVE is on a Sunday this year.

You can also use this same calculating system for 2018 and 2019, but you have to add 1 in value to each of the month for every year. However, for 2020 we’ll have to recalculate the values because it is a leap-year.

I find it very fascinating how people figure out these things. This a super useful skill to know and is perfect for me. Sure enough, I will memorize the monthly values and use this trick every chance I get. I hope you can also enjoy this new piece of information.
