What is it?
Days Between Dates counts the Days between two dates, as Weeks and days and Years, months, days, and can add or subtract days from a date.
Who is it for?
Anyone counting days to a deadline, notice period, loan due date or visa stay, and people planning events or leave.
How to use it
- Pick the Start date and End date.
- Tick Count the end date too when both days count (see below).
- Under Add or subtract days, type Days to add to the start date (use − to go back).
Should I count the end date?
- Leave it off for durations: from 1 to 10 March is 9 days later, like counting nights in a hotel.
- Tick it when both days are included: leave from 1 to 10 March is 10 days of leave.
- Legal and notice periods have their own rules; read the document’s wording.
Uses
- Days left to an exam or a loan due date.
- The date 90 days after a purchase (warranty or return window): add 90.
- Pregnancy, visa stays and notice periods.
Only calendar days are counted. For working days that skip weekends and holidays, use the Working Days Calculator.
Errors and how to fix them
- “Choose a date”: a date is empty.
- Negative days: the end date is before the start date; swap them.
