Holiday entitlement calculator: your statutory leave in days
The holiday entitlement calculator converts the UK statutory minimum of 5.6 weeks into days for your working pattern. Full time staff on a five day week get 28 days a year, part time staff get the same 5.6 weeks pro rated, and irregular hours workers accrue leave at 12.07% of hours worked.
Part time and irregular hours are where the arguments start, because holiday entitlement is a fraction of a week rather than a fixed pile of days.
