What is BST in EST?
Eastern Time is 5 hours behind
British Time is on UTC+1:00 and Eastern Time is on UTC−4:00 right now. Both are on daylight saving, so their clocks read BST and EDT. The gap changes during the year — see below.

When the difference changes
British Time and Eastern Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:
- Now – October 25, 2026Eastern Time is 5 hours behind
- October 25, 2026 – November 1, 2026Eastern Time is 4 hours behind
- November 1, 2026 – March 14, 2027Eastern Time is 5 hours behind
- March 14, 2027 – March 28, 2027Eastern Time is 4 hours behind
- March 28, 2027 – onwardsEastern Time is 5 hours behind
Periods shorter than a day are not listed: both zones change at 2am in their own local time, so there are a few hours on each transition date when the gap is briefly something else.
