What it calculates

Typical uses
Checking a 90-day notice period, counting days of stay for a visa or tax residency (182 days in India), measuring project duration, counting working days for an SLA, or finding how long until an exam or wedding.
Frequently asked questions
Does it include both the start and end date?
It counts the difference, so 1 Jan to 2 Jan is 1 day. Add one if your rule counts both days inclusively.
Does working days exclude public holidays?
No, only Saturdays and Sundays. Subtract holidays manually.
Can I count days until a future date?
Yes, enter today as the start and the future date as the end.
