Last reviewed: May 19, 2026 · Holiday data: June 23, 2026

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.
