UK holiday entitlement calculator

How many days (and hours) of paid holiday you get by law: full-time or part-time, and when you start or leave part-way through the leave year.

Paid holiday a year

16.8 days

3 days a week × 5.6 weeks

5.6 weeks of leave
126 hours
Bank holidays can count

Working 3 days a week, you get 5.6 × 3 = 16.8 days of paid holiday a year. In hours that is 126 hours, at an average working day of 7.5 hours.

Your employer can count bank holidays as part of this, and can give you more than the legal minimum but not less. Part-year results are rounded up to the nearest half day in the GOV.UK examples.

If your hours change from week to week, or you only work part of the year, you build up holiday as 12.07% of the hours you work: use the irregular hours calculator instead.
These are the rules for Great Britain. Northern Ireland has its own rules (nidirect.gov.uk).

Your numbers

example: change the numbers

Days you work in a week

The days you normally work: 5 for full-time, 3 for a three-day week. Use 2.5 if you average two and a half days. Working more than 5 days a week still gives a maximum of 28 days.

Hours you work in a week

Optional. Your usual weekly hours, to see the holiday in hours as well as days. Enter 0 to leave it out.

Days of the leave year you work for this employer

Leave 365 for a whole leave year (366 in a leap year). If you start or leave part-way through, count the calendar days you are employed in the leave year: from your start date to the end of the leave year, or from the start of the leave year to your last day.

How it works

Nearly all workers get 5.6 weeks of paid holiday a year. Multiply the days you work in a week by 5.6, up to a maximum of 28 days: 5 days gives 28, 3 days gives 16.8.
To see the holiday in hours, work out your average working day (hours a week ÷ days a week) and multiply it by the days of holiday: 30 hours over 4 days is 7.5 hours a day, and 22.4 days × 7.5 is 168 hours.
If you start or leave part-way through the leave year, take the days you are employed in the leave year ÷ the days in the leave year, multiply by the full-year days, and round up to the nearest half day.

Worked example

Someone who works 4 days and 45 hours a week and leaves on 25 July, 116 days into a leave year that starts on 1 April: 22.4 days × 116 ÷ 365 = 7.1 days. In hours, 7.1 × 11.25 = 80 hours.

Good to know

The legal minimum is 5.6 weeks of paid holiday a year, whether you work full-time or part-time, and it is capped at 28 days. Your employer may count bank holidays in it.
Your leave year is the one in your contract. If the contract does not say, it starts on the first day of the job (GOV.UK).
If you take or accrue more than the minimum, the extra depends on your contract: an employer does not have to apply all the statutory rules to extra leave.
You can usually carry over untaken leave only as your contract says. If you have 28 days, GOV.UK says up to 8 days can be carried over.
When you leave, your employer must pay you for statutory holiday you have not taken. Holiday you have taken beyond your entitlement can be deducted only if it was agreed in writing beforehand.
Workers with irregular hours or who work part of the year use a different method, with 12.07% of the hours worked. Those who work in agriculture have their own rules.

Frequently asked questions

How many days of holiday do I get by law?

Most workers get 5.6 weeks a year: 28 days if you work 5 days a week, and 5.6 times your days a week if you work fewer. The maximum is 28 days.

How much holiday do part-time workers get?

The same 5.6 weeks, pro rata. Working 3 days a week gives 3 × 5.6 = 16.8 days; working 2 days a week gives 11.2 days.

Do bank holidays count towards my 28 days?

They can. An employer is allowed to include bank holidays as part of the statutory annual leave, or to give them on top.

How is holiday worked out if I start or leave part-way through the year?

You get a share of the full year in proportion to the days you are employed in the leave year, and GOV.UK rounds the days up to the nearest half day.

What if I work irregular hours?

You build up holiday as 12.07% of the hours you work in each pay period, rather than a fixed number of days. Use the irregular hours holiday calculator.
