Northern Ireland observes 10 bank holidays in 2027: 10 fall on a weekday and 0 land on a weekend, leaving 251 working days across the year. The working week is Monday to Friday with a Saturday and Sunday weekend, the same as England and Wales; what changes is the bank holiday set.
How Northern Ireland differs from England & Wales
Northern Ireland observes every England and Wales bank holiday and layers two more on top: St Patrick's Day on 17 March and the Battle of the Boyne, also called Orangemen's Day, on 12 July. When either falls on a weekend, the bank holiday shifts to the following Monday. Nothing from the England and Wales set is dropped, so Northern Ireland has the longest bank holiday calendar of the four UK nations.
