The date
Sunday, 31 October 2027 is the last Sunday of October in 2027. It falls on Halloween, so trick-or-treaters will find it dark an hour earlier by the clock.
Planning around it
Night-time services such as trains, hospitals and care homes publish special rotas for the repeated hour. Anything scheduled between 01:00 and 02:00 on that morning needs a clear note on whether it means BST or GMT.
