An online date calculator helps you to calculate the number of days between two dates. It also adds or subtracts years, months, weeks, or days from a given date. Moreover, this date counter helps you to perform date calculations even if Saturday is your working day.

Simply, you can try an online day calculator to determine the number of days between two dates, but if you want to calculate it yourself, then swipe down!

Imagine that you have a difficult project due at your workplace and you are given specific days between 2 dates to accomplish it. Now suppose you have the following two situations:

- You need to calculate the date on which the progress check will take place and the due date is 27 December while the initial date is 14 October?
- You have to calculate the days you have before the progress check takes place?

**Date = final date – 14 days**

**Date = 27 – 14**

**Date = 13**

So, the progress check will take place on 13th December.

**Number of days: 365 (year – 1) = (year – 1 / 4) -) – (year – 1 / 100) + (year – 1 / 400) + d + 367-362/ 12 = 61 days**

The result will be 61 days that you have left to complete your work.

The date calculator online becomes very useful if you want to check out:

- How many days since quarantine started

In a new cell, all you need to type in =DATEDIF(A1,B1,”Y”). The “Y” indicates that you had the information, which was reported in years. This will provide you with the number of years between the two dates. Want to determine the number of months or days between two dates, then simply type into a new cell: ==DATEDIF(A1,B1,”M”) for months or =DATEDIF(A1,B1,”D”) for days.
