EVERYDAY / CALCULATOR
Days Between Dates Calculator.
Count days and weeks between two calendar dates.
LET’S WORK IT OUT
Your numbers, your answer.
THE WHY BEHIND THE ANSWER
How it works.
The difference counts elapsed calendar days between the two dates; it does not add an extra day for inclusive counting.
THE FORMULADays between dates = absolute difference between calendar dates
Worked example
From January 1 to January 8 is 7 days, or exactly 1 week.
Good to know
Both past and future dates work. The calculator uses calendar dates, independent of the local clock.
ONE MORE THING
Does this count both the start and end date?
No. To count both endpoints inclusively, add one day to the result.
