How to use this date calculator
- Pick the start date in the first box and the end date in the second box.
- Press Calculate Difference. You will see the gap in years, months and days, plus the total days, weeks and months.
- The order does not matter — if the start date is later than the end date, the calculator swaps them automatically. Nothing you type is sent anywhere; the calculation happens on your own phone or computer.
Frequently asked questions
How many days are there between two dates?
Enter both dates above and the calculator counts every day in between, including leap days, and shows the total days as well as the gap in years, months and days.
Does it count the start and end dates?
The total days figure is the number of days from the start date up to the end date — the standard way date differences are counted.
Can I use it for past and future dates?
Yes. Any two dates work — a past date and today, two future dates, or two dates years apart.
Is my data stored or shared?
