Part-time bank holiday calculator for 2027

For a January–December leave year, find the exact bank holidays that fall on your normal workdays, total the hours, then compare what happens under four common contract policies.

Your regular working week

Count hours, not rounded days.

This comparison is for someone employed from 1 January to 31 December 2027 with fixed weekly hours, the same normal weekdays and a calendar-year leave allowance. Use the allowance your employer has already confirmed in hours.

1. Which bank-holiday calendar applies?
2. Which weekdays do you normally work?
3. Are your working days the same length?

If your contract states days, ask payroll or HR for the hour-equivalent instead of guessing.

5. What does your contract say about bank holidays?

This compares booking impact only. It does not determine pay, workplace closure or contractual entitlement.

Worked example · no calculator needed

Monday-heavy patterns feel the difference.

England and Wales, six paid hours per working day, 100.8 hours confirmed for the full year, with bank holidays included and the workplace closed.

MTWTF

Monday–Wednesday

Six closures collide: 29 March, 3 May, 31 May, 30 August, 27 December and 28 December.

Bank-holiday hours
6 × 6h = 36h
Left to request
100.8h − 36h = 64.8h

MTWTF

Wednesday–Friday

Two closures collide: New Year’s Day on 1 January and Good Friday on 26 March.

Bank-holiday hours
2 × 6h = 12h
Left to request
100.8h − 12h = 88.8h

24 hours apart: both patterns work 18 hours a week and start with the same confirmed allowance. The difference appears only when the contract includes bank holidays and requires leave for closures on normal workdays.

Questions this comparison can answer

Before you subtract a bank holiday.

Are bank holidays automatically paid leave?

No. GOV.UK says an employer does not have to provide paid leave on bank or public holidays. Your contract may make them part of your annual allowance, add them separately, or treat them as normal working days.

Can bank holidays be included in the 5.6-week minimum?

Yes. GOV.UK says an employer can include bank holidays within statutory annual leave. This calculator compares that scenario with no deduction; it does not decide which policy your contract uses.

Can a non-working bank holiday be deducted?

For Great Britain, Acas says an employer cannot make a worker use holiday entitlement for a bank holiday that falls on a day they do not usually work. The collision list therefore counts only the normal workdays you select. Northern Ireland users should check the linked nidirect guidance and their contract.

Why use hours instead of rounded days?

Part-time and compressed-hours days can be different lengths. Hours preserve the exact cost of each closure and avoid silently rounding down a fractional entitlement or unequal shift.

What if my leave year starts in April?

Do not use the remaining-balance result. This version covers only a leave year from 1 January through 31 December 2027. A different 12-month window can contain a different set of bank holidays; ask your employer for the applicable dates and confirmed allowance.
