## Calculate days between two dates

If you want to know how many hours or days there are between one date and another, our online calculator is here to help you.

Perhaps you want to find out exactly how old you are, or work out how many days there are until your next birthday. Or, maybe you're looking to calculate the number of hours or days until you retire. Whatever the reason, this calculator is here to help you. This tool is a sister of the how many days until calculator.

### Calculating time manually

You can, of course, calculate the days or time between two dates manually, and should you wish to go down that route you'll need to remember how many days there are in each month. We know that there's 365 days in a regular year. If there's a leap year involved then an extra day is added. A leap year occurs every 4 years and means that February has 29 days instead of 28.

Then we get into months and the mnemonic to help remember the number of days in each:

"Thirty days have September, April, June, and November. February has 28 alone (or 29 in a leap year), And all the rest have 31."

So, calculating the number of days between two given dates isn't the easiest task because of the way in which our Gregorian calendar works (we've been using the Gregorian calendar for over 436 years, but many people question why we still use it).

The **days between dates calculator** on this page works by getting the time stamp of the start date and deducting it from the end date (or vice-versa if the end date is in the past) before
calculating the number of hours, days and years between them.

## How many days since I was born?

To **calculate the number of days since you were born**, simply enter your date of birth as the **start date** and then
ensure that the **end date** is set to today's date (if it isn't already set, click the 'today' link that appears to the right of the box). Then click the 'Calculate' button. Alternatively,
you could give my age calculator a try.

As well as telling you how many days you've been on our planet, my calculator is also able to work out what day you were born on. As an alternative, you could try the birthday calculator, which will show you all sorts of fun facts about your birthday, including the day on which you were born.

In a world where privacy of personal data is hugely important, please rest assured that I do not store any of the information you enter into my date calculator.
