Understanding holiday entitlement for starters and leavers

The full-year figure comes first

For many regular workers, the usual starting point is weekly working days multiplied by 5.6. Someone working 5 days a week often sees this described as 28 days. Someone working 3 days a week would usually start from 16.8 days before any employer extras are considered.

That does not mean every workplace shows entitlement in exactly the same format. Some use days, some use hours, and some separate contractual leave from bank holidays.

Starters and leavers need a part-year calculation

If someone starts halfway through the leave year, they normally only need the portion of annual leave that relates to the part of the year they will work. The same idea applies when someone leaves before the year ends.

This is where small wording differences matter. "25 days plus bank holidays" is not the same as "33 days including bank holidays". The number can look similar, but the booking rules may be different.

Common places holiday estimates go wrong

Irregular hours need extra care

When hours vary, entitlement is often easier to understand in hours rather than days. This avoids pretending that every "day off" has the same value when shifts are different lengths.

For irregular-hours and part-year workers, GOV.UK explains that leave can build up based on hours already worked. In real life, that means the right answer may depend on the leave year, the pay period and the worker type.
