What actually happens when the clocks spring forward?
Direct answer. At exactly 01:00 GMT on the last Sunday of March, UK clocks move straight to 02:00 BST. The hour between 01:00 and 02:00 simply doesn’t exist that night.
From that moment the UK is on British Summer Time (UTC+1), one hour ahead of GMT, until the last Sunday of October. Internet-connected devices update themselves; manual clocks need a nudge.
Key fact: Spring forward = lose 1 hour. 01:00 GMT becomes 02:00 BST on the last Sunday of March.
