Date duration calculator
The distance between
any two dates.
Pick a start date and an end date and EPOCH measures the gap — total days, weeks, months and years, down to the second. It works just as well for a past anniversary as for a deadline still ahead.

One span, every unit
The headline gives the human-readable breakdown — “2 years, 3 months, 11 days” — while the grid restates the same interval as a single running total in each unit. Both come from walking the real calendar, so leap years and uneven months never throw the count off.
If one of your dates is a birthday, the age calculator frames the result more naturally, with a live seconds counter when the end date is today.
Frequently asked questions
How do I count the days between two dates?
Enter the earlier date in the first field and the later date in the second. EPOCH shows the total number of days, plus the same gap as years, months, weeks, hours, minutes and seconds.
Does the count include both the start and end dates?
The result is the elapsed interval — the time from the start of the first date to the start of the second. If you need to count both endpoints inclusively, add one day to the total-days figure.
Can I measure time until a future date?
Yes. Put today (or any date) first and a future date second to count down to a deadline, event or anniversary.
How is this different from an age calculator?
It is the same engine without the birthday framing. An age calculator measures from a birth date to today; this measures between any two dates you choose.
