Time in Chelmsford, United Kingdom

Time zone: BST (UTC/GMT +01:00) — Europe/London

Chelmsford keeps BST (1 hour ahead of UTC, UTC+01:00). Its database zone is Europe/London — worth knowing if you are scheduling anything that has to survive a daylight saving change.

This zone does shift. On Sunday, 25 October 2026 the clocks go back 1 hour and Chelmsford moves to GMT, so anything booked across that date needs checking.

Chelmsford has roughly 111,511 residents and ranks 88th by population among the United Kingdom cities on this site.

Current gap between Chelmsford and cities people most often need to coordinate with. These figures already account for daylight saving where it applies.

Assuming a 09:00–17:00 day at both ends, these windows (in Chelmsford local time) fall inside working hours for both cities.

No shared working window exists with Los Angeles, Tokyo or Sydney, so those calls have to sit outside somebody's normal hours.

Same zone, same time — each of these sits on Europe/London alongside Chelmsford, including through any clock change.
