UK Holiday Entitlement Calculator
Your statutory paid holiday in the UK, for full-time, part-time and irregular hours.
Good to know. Bank holidays are part of the 28 days, not on top of them, unless your contract says otherwise.
How it works
In plain words
Everyone gets 5.6 weeks of paid holiday a year. Multiply 5.6 by the days you work a week, up to 28 days, or by your weekly hours. For part of a year, take the share of the year you are employed. With irregular hours, holiday builds up at 12.07% of the hours you work.
The formula
days = 5.6 × days a week (max 28) × months ÷ 12 hours = 5.6 × hours a week × months ÷ 12 irregular hours = hours worked × 12.07%
Worked example
Working 3 days a week: 5.6 × 3 = 16.8 days of paid holiday a year, bank holidays included.

About the UK holiday entitlement calculator
Almost every worker in the UK has the right to 5.6 weeks of paid holiday a year. For someone working five days a week, that is 28 days. Employers can include the eight bank holidays in England and Wales in the 28, or give them on top; the contract says which.
Part-time workers get the same 5.6 weeks, in proportion to the days or hours they work: 16.8 days for three days a week, or 5.6 times their weekly hours. Someone working six or seven days a week still gets a statutory maximum of 28 days. Anyone starting or leaving part way through a leave year gets the share for the time they are employed; many employers round fractions of a day up.
Since 1 April 2024, workers with irregular hours, such as zero-hours contracts, and people who work only part of the year build up holiday at 12.07% of the hours they work in each pay period. The 12.07% comes from 5.6 weeks divided by the 46.4 weeks left in a year after them.
Contracts can give more than the legal minimum, and many do. This calculator shows the statutory entitlement only. Northern Ireland has the same 5.6 weeks with its own rules, and the self-employed have no statutory holiday.
