How Works Date To Date Calculator ?

A practical way of date duration calculator without using computer :

Write two dates in the top, write the smaller one in the bottom.

For example ;






Start processing from the left. In our example, we will first remove 5 to 11. So it's 5, 35 (we add 30 days of a month). 35 - 11 = 24.

Then we go to the month section. We took a month from the month which was 10 and we added it to the day. Here we find 9 - 9 = 0 months. Finally, we take years out of each other. 2019 - 1993 = 27. The difference between dates is 29 years, 0 months and 24 days. If the upper month is bigger than the bottom, we will add 1 year or 12 months on the right. For example, if the upper month is 7, the lower 9. We add to the 12 months of the year 7. So the upper month is 12 + 7 = 19. Then we take 9 out of 19 and find 10 as the month difference. Therefore, the upper year will be reduced. Thanks to this way you can find date to date calculator without using computer.
