Calendar days include weekends and bank holidays. This is not a working-days or legal-deadline calculator.
How it works
Elapsed days are the difference between the two calendar dates. Inclusive counting adds one day. Weeks are complete seven-day blocks plus the remainder.
A quick example
1 January to 8 January is 7 elapsed days, or 8 days when both dates are included.
Good to know
Why does the same date show zero?
No time has elapsed between identical dates. Select inclusive counting to count that date as one day.
Does daylight saving change the answer?
No. This calculation compares calendar dates, so clock changes do not add or remove a day.
