What happens when a bank holiday falls on a weekend?
You get a weekday instead
A “substitute day” becomes the bank holiday, normally the following Monday (or Tuesday, if Monday is already one). The government sets these, and gov.uk lists them. In 2027, Christmas Day is a Saturday, so the bank holiday is Monday 27 December.
Every substitute day, 2026 to 2028

Over Christmas 2027: Christmas Day (25 December) falls on a Saturday, so the bank holiday is Monday 27 December. Boxing Day (26 December) falls on a Sunday, so the bank holiday is Tuesday 28 December. New Year’s Day (1 January) falls on a Saturday, so the bank holiday is Monday 3 January.
What it means for you
- The substitute day is the bank holiday. If your employer gives bank holidays off, it's the substitute day you get, not the Saturday or Sunday.
- Part-time and don't work Mondays? A substitute Monday lands on a day you don't work, the same as any Monday bank holiday. How that's handled depends on whether your bank holidays are pro rata. Part-time workers and bank holidays.
- Christmas years like 2027 are good value. With the bank holidays on Monday 27 and Tuesday 28 December, three days of leave bridge to New Year. Christmas 2027: the days to book.

More questions
Is the substitute day always a Monday?
Usually. When two bank holidays fall on the same weekend, such as Christmas Day on a Saturday and Boxing Day on a Sunday, the substitutes are the Monday and the Tuesday.
Do I get the actual day off as well?
Not as an extra bank holiday. The substitute day replaces the weekend date. Whether you work on the weekend day itself is up to your employer and contract.
