About this tool
Pick a start and an end date to see the gap as years, months and days, as a total number of days, as weeks and days, and as business days (Monday to Friday). Use it for project deadlines, notice periods, trip countdowns and contract terms.
How to use it
- Choose the start date and the end date.
- Tick 'Include the end date' if you want both days counted.
- Read the difference in calendar and business days.
Frequently asked questions
Does it include the end date?
By default no, so 1 January to 2 January is 1 day. Tick the option to count both dates.
Are public holidays excluded from business days?
No. Business days only skip Saturdays and Sundays because holidays differ by country.
What if the end date is before the start date?
The tool swaps them for you and tells you the dates were in reverse order.
