Calculate the difference
About this calculation
Enter any two dates and this calculator returns the number of days between them, broken down into calendar days, weeks and remainder days, approximate months, business days and weekend days.
The count is inclusive of both endpoints — that is, 1 January to 2 January returns 2 days. If you need the difference excluding the start date, subtract one.
Business days count Monday to Friday and ignore public holidays, which vary by country.
Frequently asked questions
Is the result inclusive or exclusive?
Both endpoints are counted, so the result is one more than the mathematical difference between the two dates. Subtract 1 if you want the number of days elapsed.
Why does the month figure say "approximately"?
Months range from 28 to 31 days, so there is no single exact conversion. The figure divides by 30.44, the average month length.
Do you exclude public holidays?
Not automatically, because holidays differ by country and year. The business day figure only excludes Saturdays and Sundays.
Can I use it for notice periods or deadlines?
Yes, but always confirm whether your contract or rule counts calendar days or working days — the two give very different answers over a long period.
