How do calculate the days between two different dates?

Day counter comes in handy if you are working on any complicated projects that require you to give the total estimate time. Let's discuss it with an example.


Suppose you get an urgent project to work on from your office. Let's assume that today is 15th August. Your company is expecting to get the project completed by 28th October. But the boss does not want to play around with last minutes messes or errors. Hence, the boss asked you to share the presentation of the project at least 14 days before the project submission date.

Now you will be wondering how many days do you have to complete the project. So, here you will need to first calculate the total number of days between 15th August and 28th October. Let's calculate it manually.

  • There is a total of 31 days in August, 30 days in September, and 31 days in October.
  • The project starts on 15th August.
  • So, you have 31 - 15 = 16 days of August.
  • Also, you have September full month. So, you will get 30 days of September.
  • Lastly, the project completion date is 28th October. Therefore, you have 28 days of October.
  • Total will be: 16 + 30 + 28 = 74 days

As a result, you will get 74 total working days to work on project.

Now you need to subtract the 14 days from the final submission day. Because boss wants 14 days early presentation.

Therefore, 74 - 14 = 60 days

Finally, you will get a total of 60 days. So ideally you will have 60 days to finish your project.
