How the count works
The date is today plus 21 calendar days, so it falls on the same weekday as today, a Monday. Working days run from today to the day before 19 Oct 2026, Monday to Friday, less bank or federal holidays.
21 days from other start dates
Starting on a different day changes the end date and the working days, because weekends and holidays fall differently. Working days count the start date but not the end date.

Sources and assumptions
- Calendar days: the target date minus today. Working days: Monday to Friday from today up to the day before the target date, the way the Days Between Dates calculator counts them.
- UK working days take off England and Wales bank holidays from the GOV.UK feed, including substitute days. Scotland and Northern Ireland have different bank holidays.
- US working days take off federal holidays on the day they are observed under 5 U.S.C. 6103. States and employers can add their own holidays.
Dates are worked out for the UK time zone and refreshed in your browser for your own date. Your employer, court or contract may count days differently, so check the exact rule that applies to you.
