How we calculate UK annual leave entitlement
All results are based on the Working Time Regulations 1998 (as amended 2024).
This is one of the most comprehensive free annual leave calculators available online. Unlike simpler tools that only handle full-time workers, ours covers common scenarios UK employees and HR teams face — with real bank holiday dates built in for all three UK nations.
- Full-time & part-time workers
- Accrual for new starters & leavers
- Bank holiday data: England & Wales, Scotland, Northern Ireland
- Days and hours modes
- FTE or actual part-time entitlement
- Always rounds up, never down
Full-time workers
The UK statutory minimum is 5.6 weeks per year. For a standard 5-day week that equals 28 days. Your employer may offer more — enter your actual entitlement above.
Holiday entitlement for part-time workers
Part-time employees receive the same 5.6 weeks entitlement as full-time staff, scaled to the number of days they work. Results are always rounded up to the nearest half day — never down.
Accrued holiday & pro-rata
For new starters or anyone leaving part-way through the year, we calculate accrued holiday as the proportion of the leave year worked. Enter your start or end date in the Pro-Rata section above.
Bank holidays
The statutory 28 days can include bank holidays — employers are not required to offer them on top. England & Wales have 8, Scotland 9, Northern Ireland 10.
Rounding rules
UK law does not specify rounding, but government guidance states entitlement should be rounded up where it results in a partial day. For a typical worker this equates to roughly 2.3 days per month. We always round up, never down.
Holiday when leaving a job
If you leave part-way through the year, you are owed any accrued but untaken leave. Use the employment end date in the Pro-Rata section to calculate exactly how many days are owed.

UK Annual Leave — The Rules
A plain-English summary of your statutory rights under UK employment law.
The statutory minimum is 5.6 weeks per year, capped at 28 days for most workers. For a standard 5-day week that equals exactly 28 days. Employers can offer more than this — many do — but they cannot offer less. Bank holidays can be counted as part of this entitlement or offered on top, depending on your contract.
Part-time workers receive the same 5.6 weeks, calculated pro-rata based on the number of days they work. A 3-day week gives 16.8 days (rounded up to 17); a 4-day week gives 22.4 days (rounded up to 22.5). Part-time workers cannot be treated less favourably than comparable full-time colleagues — this is a legal right under the Part-Time Workers Regulations 2000.
The January 2024 reforms to the Working Time Regulations introduced new rules for irregular-hours and part-year workers (such as term-time and zero-hours staff). For these workers, holiday now accrues at 12.07% of hours worked in each pay period, rather than as a fixed annual allowance. This change applies to leave years beginning on or after 1 April 2024.
Holiday continues to accrue during maternity leave, paternity leave, and statutory sick leave. If an employee is unable to take accrued leave during these periods, they have the right to carry it forward into the next leave year.
Frequently asked questions
-
In the UK, most workers are entitled to a minimum of 28 days (5.6 weeks) of paid annual leave per year. For a 5-day week that means 28 days; for a 4-day week, 22.4 days (rounded up to 22.5); for a 3-day week, 16.8 days (rounded up to 17). Use the calculator above to get your exact figure based on your working pattern and contract.
-
The minimum statutory holiday entitlement under the Working Time Regulations 1998 is 5.6 weeks per year, capped at 28 days for full-time workers. This works out to roughly 2.3 days per month. Bank holidays can be counted as part of this 28-day minimum — your employer does not have to offer them on top. There is no upper limit on what an employer can offer voluntarily.
-
Full-time employees working a 5-day week are entitled to a minimum of 28 days (5.6 weeks) of paid annual leave per year under the Working Time Regulations 1998. This can include the 8 public bank holidays in England and Wales. Your employer may offer more than this statutory minimum.
-
Part-time workers receive the same 5.6 weeks entitlement as full-time staff, but calculated on the number of days they actually work per week. For example, someone working 3 days per week gets: 3 × 5.6 = 16.8 days, which rounds up to 17 days. Part-time workers cannot be treated less favourably than full-time equivalents.
-
It depends on your contract. UK law allows bank holidays to count as part of the 28-day statutory minimum — employers are not required to give bank holidays on top of the 28 days. However, many employers do offer bank holidays in addition. If your 28-day allowance includes bank holidays, you effectively get 20 days to book freely (28 − 8 bank holidays = 20 days).
-
For a new starter, divide the number of days remaining in the leave year (from their start date) by the total days in the leave year, then multiply by their full annual entitlement. Always round up the result. For example, an employee starting on 1 October with a leave year running 1 April to 31 March would have 183 days remaining out of 365: 183 ÷ 365 × 28 = 14 days.
-
England & Wales have 8 public bank holidays per year. Scotland has 9 (the additional day being 2 January and St Andrew's Day replacing one of the spring bank holidays in the schedule). Northern Ireland has 10 public holidays, including St Patrick's Day (17 March) and the Battle of the Boyne / Orangemen's Day (12 July).
-
Yes. Statutory annual leave continues to accrue during maternity leave (including Additional Maternity Leave), paternity leave, and periods of statutory sick leave. If an employee was unable to take accrued leave during these periods, they may be entitled to carry it over into the next leave year.
-
If you leave part-way through a leave year, you are entitled to the proportion of your annual leave that you have accrued up to your last day. The formula is: annual entitlement × (days worked in leave year ÷ total days in leave year), then subtract any leave already taken. Enter your employment end date in the Pro-Rata section of the calculator above — it will work this out automatically. Any outstanding days should be paid out by your employer.
-
Yes — any accrued but untaken leave that you were unable to take before your last day must be paid out by your employer. This is called Payment in Lieu of Notice (PILON) for the holiday element. To calculate the monetary value, divide your annual salary by 260 (for a 5-day week) and multiply by the number of outstanding days. This calculator tells you the number of days owed; for the monetary value, see GOV.UK holiday pay guidance ↗.
