How to Calculate it Yourself

To find the number of days between two dates, we can count the days step-by-step.

Example: How many days from March 28 to April 3?

Step 1: Count the days left in the first month.
March has 31 days.
From March 28 to the end of March is: 31 − 28 = 3 days.

Step 2: Add the days in the next month.
We want to reach April 3, so we add 3 days.

Step 3: Add them together.
3 days (in March) + 3 days (in April) = 6 days.

For longer periods we can add the full months in between. Just remember how many days are in each month!

Including the Start and End Days?

Usually "days between" means we do not count the start day, but we do count the end day. This is how most calendar calculators (including ours above) work.

For example, from Monday to Tuesday is 1 day.

But if you want to know how many days you will be on vacation, you might want to count both days (inclusive). In that case just add 1 to your result.
