Working Days in October 2025

October 2025 has 31 calendar days, of which 8 fall at the weekend. It opens on a Wednesday and closes on a Friday, and contains 4 Mondays — useful to know if your payroll or reporting cut-off lands on a particular weekday.

There are no bank holidays in October 2025in England & Wales, so the 23 working days are simply every weekday in the month. Scotland or Northern Ireland may still differ — check the cards above.

October 2025 has the same number of working days as October 2024 (23).

Across the year, October has the second-most working days of any month in 2025in England & Wales — it is one of the fullest months, giving the most capacity before leave is booked. All three UK regions share the same total of 23 working days this month.

For HR and payroll, the working-day count drives pro-rata pay for anyone starting or leaving part-way through October, and the number of Mondays affects weekly-paid staff and any cut-off tied to the start of the week. For project and finance teams, it sets the realistic capacity for the month before leave is even taken into account.

Working days are counted Monday to Friday, excluding the bank holidays shown above for the region you choose. Scotland and Northern Ireland carry extra holidays — Scotland’s 2nd January, St Andrew’s Day, and an early-August Summer holiday; Northern Ireland’s St Patrick’s Day and Battle of the Boyne — so a UK-wide team can have three different figures for the same month.
