How many days are between two dates?

Enter both dates above. The tool shows the exclusive count, which is the standard meaning of days between, alongside the inclusive count that includes both endpoints.

Does this count business days?

Yes, excluding Saturdays and Sundays. It does not account for public holidays, which differ by country and year, so subtract those yourself.

Should I count the first day?

It depends on the situation. Contracts and deadlines usually count inclusively, while the plain phrase days between usually does not. Both figures are shown so you can pick.

How do I add days to a date?

Use the add or subtract tab, enter a starting date and a number of days, and it returns the resulting date with the weekday.

What do you need?

Start date

Defaults to today.

End date

Pick both dates. Order does not matter, since the result is the span either way.

Working days exclude Saturdays and Sundays only. Public holidays vary by country and year, so subtract those yourself if you are counting toward a deadline.

Inclusive or exclusive counting

This is the question that makes two people disagree about the same span. From Monday to Friday is four days if you count the gaps and five if you count the days themselves.

The default here is exclusive, which counts the gaps, because that is what "days between" normally means and what date arithmetic produces. The inclusive count is shown alongside so you can use whichever the situation calls for.

Working days exclude weekends only

The business day count removes Saturdays and Sundays. It does not know about public holidays, which vary by country and by year and would need a calendar this tool deliberately does not carry.

If you are counting toward a deadline in a specific country, subtract the holidays yourself. Getting that wrong by a day or two is the usual failure here.

Why months are approximate

The result in months is a calendar count, so it lands on the same day number where one exists. Where it does not, such as 31 January plus one month, it falls back to the last day of the shorter month.

Days and weeks are exact. Months and years are conventions, and any tool that tells you otherwise is hiding a decision it made on your behalf.
