Calculate dates and times
Our date calculators can be used to calculate a future or past date if you add or subtract a number of years, months, weeks, days, hours or minutes. To make a calculation, simply follow these steps:
- Enter a start date in the start date box.
- Enter a start time, if necessary.
- Select either the add or subtract option.
- Enter a number into any of the boxes for days, weeks, months, years, etc.
- Click Calculate.
Let's look at an example...
What is the date 6 months from today?
The date 6 months from today is June 08, 2025, based upon the UTC time zone.
To work this out using our calculator, simply select today's date (if it isn't already there) and enter the number 6 into the years box.
Countdown to a date
You can use our calculator to see a live countdown to a future event or date of your choice.
- Select the countdown tab.
- Enter a date into the countdown to field and enter a time if necessary.
- Enter a name for the event, if you wish (or select an event from the dropdown list).
- Click on Calculate.
Difference between two dates
Shared with our days between dates calculator, our calculator helps you to work out the number of years, months and days between two dates. So, you may wish to know how long an event lasts or how long it has been since something specific happened. Or, you may wish to find out how old you were on a certain date in the past or how old you will be on a date in the future. If your start date is set to today's date, and you're looking at a future date, our calculator will provide you with a countdown to the date.
How long until my next birthday?
If you can't wait until your next birthday and want to know how long you have to wait, you can use our 'difference between dates' calculator to help you. It'll even give you a date countdown. This calculation is shared with our how many days until calculator. Here's the instructions:
- Select the difference between dates tab.
- Ensure that today's date is selected in the start date field.
- Enter the date of your next birthday in the end date field.
- Click on Calculate.
How old am I?
You can use the add to a date calculator to find out how old you are. Here's how:
- Enter your date of birth in the start date field.
- Ensure today's date is entered in the end date field.
- Click on Calculate.
As an alternative, you can use our age calculator, which gives you a lot of extra information about your age.
Countdown to Christmas/Easter/Halloween
Our third date calculator allows you to see a countdown combination of years, months, days, hours and minutes to a number of different yearly events such as Christmas, Easter, Halloween and New Year's Eve. As we mentioned earlier, you can also enter your own information to see a countdown to your own, personal event.
