Fixed four-day-week quick answer

A Monday–Thursday week makes the Christmas boundary unusually efficient.

If Friday is always a normal non-working day, two proposed leave days can join Christmas, New Year and two weekends into an 11-day break. The result depends on the relevant bank holidays also being confirmed non-working days for you.

Request Wednesday 29 and Thursday 30 December 2027.

The break runs from Friday 24 December 2027 through Monday 3 January 2028. It assumes a fixed Monday–Thursday week, usual weekends off, and 27–28 December plus the 3 January 2028 substitute holiday confirmed as non-working.

Pattern scope

Fixed repeating weekdays—not a rotating schedule.

“Four-day week” can describe different contracts. This page models only a schedule with the same normal working weekdays every week.

Fits

Mon–Thu or Tue–Fri

Select four fixed normal workdays and enter a confirmed whole-day planning balance.

Does not fit

4-on-4-off rotation

A repeating shift cycle moves across weekdays. Use the dedicated 4-on-4-off planner.

Does not fit

9-day fortnight

An alternating day off needs a two-week cycle. Use the 9-day-fortnight planner.

A fixed four-day week may be part-time, compressed full-time hours or another agreed arrangement. This planner does not calculate entitlement or convert longer compressed days into hours. Use only a whole-day balance your employer has already confirmed.

Exact worked example

How two proposed leave days could create 11 days away.

The two leave dates remain inside calendar year 2027. The natural break continues into 2028 because the usual Friday and weekend are followed by the official New Year substitute holiday on Monday 3 January.

Your normal day off matters

Monday–Thursday and Tuesday–Friday unlock different dates.

The planner counts a bank holiday only when it falls on a normal working day and your employer confirms it is non-working.

The Tuesday–Friday example proposes 23–25 March for 10 days away from 20–29 March. Monday is already the normal day off; Good Friday is the distinct bank-holiday support. Regional and employer rules can change which holidays are non-working.

Before requesting

Confirm the pattern, day length and holiday policy.

The dates above are proposals, not an employer decision. Verify the official dates on the GOV.UK bank-holiday calendar, including the adjacent 2028 boundary.

Acas flexible-working guidance explains that compressed hours can mean working the same hours over fewer days. Longer compressed days may need to be booked and tracked in hours rather than the equal whole days used here.

Acas bank-holiday guidance and GOV.UK holiday-entitlement guidance explain that contract terms control bank-holiday treatment and that employers can include bank holidays within statutory leave.

If your allowance is recorded in hours, use the part-time bank-holiday calculator to check holiday collisions, then confirm proposed leave hours with your employer before committing to travel.
