Calculate holiday allowances: Know exactly how much leave everyone’s entitled to – full-time staff, part-time staff, mid-year starters and departing employees.

How does it work?

We’ve assumed you’re a UK company and your holiday year runs with the calendar year (starts 1st January 2025, ends 31st December 2025).

Each employee has a statutory minimum entitlement of 5.6 weeks, which works out as 28 days for a full-time team member working five days per week. This figure can include Bank Holidays and national holidays, if you wish.

Part-time employees are entitled to the same amount of holiday, but pro rata. Legally, this allowance must be rounded up (not down) to the nearest day – so someone working 3 days per week is entitled to 16.8 days’ holiday, rounded up to 17.
