Working Days in January 2025

January 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 is 1 bank holidayin England & Wales this month: New Year’s Day on Wednesday 1 January. 22 working days remain once it is removed along with the weekends.

January 2025 has the same number of working days as January 2024 (22).

Across the year, January has the fourth-most working days of any month in 2025in England & Wales. The regions differ this month: England & Wales 22, Scotland 21, Northern Ireland 22.

For HR and payroll, the working-day count drives pro-rata pay for anyone starting or leaving part-way through January, 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.
