How are bank holidays treated?

UK law doesn't require employers to give bank holidays on top of the statutory 5.6 weeks — but whichever approach is used, it must be clearly set out in your employment contract. ACAS guidance on bank holidays ↗

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.

5 days × 5.6 weeks = 28 days

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.

Days/week ÷ 5 × 28 = entitlement

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.

Days worked ÷ 365 × entitlement

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.

Check your contract for how bank holidays are treated

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.

Always rounded up to nearest 0.5 day

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.

Did you know? The average UK employee took 33.9 days of leave in 2023 — down from 38 days in 2020 (Sage, 2024). Meanwhile, unused leave per employee has fallen by 71% since 2019, from 18.5 days to just 5.3 days. If your result above is lower than 33.9 days, it may be worth checking your contract.
