Pick two dates. Calendar days, weeks and weekdays — with the option to count both the start and end date.
Results update as you type.
From 1 July to 3 July is 2 days apart, but 3 days if you count days covered. Periods "from" one date "to" another on forms often count both days, so the box starts ticked; untick it for plain elapsed time.
Dates are worked out in UTC, so a daylight-saving change can't add or remove a day, and leap years are handled.
1 July 2025 to 3 April 2026, counting both dates, is 277 days — the kind of count entered on a tax form for part-year residency or a Medicare levy exemption.
Weekdays exclude Saturdays and Sundays only; public holidays vary by state and aren't removed.
365. 1 July 2026 to 30 June 2027 has no 29 February, so counting both ends gives 365 days.
Include it for days covered, such as leave or residency days; leave it out for elapsed time until an event.
