For planning, not for deciding. This tool gives estimates to help you plan and compare. It is not financial, tax, legal or medical advice, and it should not be the only thing you base a decision on. Check the numbers with your bank, lender, advisor or doctor before you act.

How it works

The total days figure is the number of days from the first date to the second, not counting the first day. Dates one day apart give 1.

The years, months and days figure follows the calendar. The weekday count counts Monday to Friday only and ignores public holidays.

The order of the dates does not matter. The calculator always works out the gap from the earlier date to the later one.

Good to know

To include both the first and last day, add 1 to the total.

For notice periods, check whether your contract counts calendar days or working days.

Frequently asked questions

Does it count the first day?

No. It counts the days from the first date to the second. Add 1 if you want to count both ends.

Are weekends and holidays excluded?

The total includes every day. The weekday figure excludes Saturdays and Sundays but not public holidays, which vary by place.

How do I count days from today?

Set one of the dates to today’s date.
