Days Between Dates
Count the exact number of days between any two dates — with the same gap shown in weeks, months and years. Pick a start and end date and the answer updates instantly.
How to count days between two dates
Choose a From date and a To date and the calculator subtracts one from the other to give the whole number of days in between. Tick Include the end day to count both endpoints (handy for booking nights or counting inclusive days).
The same span is also broken down into weeks plus leftover days, an approximate number of months, and years — so you can read the gap whichever way suits you.
Frequently asked questions
How many days are between two dates?
Subtract the earlier date from the later one. This tool does it for you: pick both dates and it shows the exact day count, plus weeks, months and years.
Does it include the start and end day?
By default it counts the days in between (end minus start). Tick “Include the end day” to count both endpoints, which adds one day to the total.
Are leap years handled?
Yes. The calculation uses real calendar dates, so February 29 and leap years are counted correctly.
