Imagine that you have a complicated project due at work. Today is July 14. Your boss wants to check the progress 14 days before the end of the project. Additionally, he expects the project to be finished by September 27.

You can ask yourself two questions:

On what date will the progress check take place?

How many days do you have before the progress check?

To answer the first question, we need to subtract 14 days from the date of September 27. If you input 14 days as the days between, and September 27 as the end date into the day counter, you will quickly discover that the progress check will take place on September 13.

Now that we know when the progress check will happen, we can calculate the number of days between dates of July 14 (the start date) and September 13 (the end date.) The result is 61 days - that's the amount of time you have left to work on your project.
