📘 About the UK Holiday Entitlement Calculator

Almost every UK worker is entitled to 5.6 weeks' paid holiday a year. Someone working 5 days a week gets 28 days, which can include the 8 bank holidays. The legal maximum is 28 days, even for 6-day workers. Part-time workers get the same 5.6 weeks pro-rata.

People who start or leave during the year get a share of the year's leave. For irregular-hours and part-year workers, holiday builds up at 12.07% of hours worked in each pay period (leave years from 1 April 2024).
