What is WET in GMT?
Greenwich Mean Time is 1 hour behind
Western European Time is on UTC+1:00 and Greenwich Mean Time is on UTC+0:00 right now. Western European Time is on daylight saving, so its clocks read WEST. The gap changes during the year — see below.

When the difference changes
Western European Time and Greenwich Mean 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, 2026Greenwich Mean Time is 1 hour behind
- October 25, 2026 – March 28, 2027Greenwich Mean Time is the same time
- March 28, 2027 – onwardsGreenwich Mean Time is 1 hour 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.
Daylight saving
Western European Time
Clocks go back one hour at 2am local time, becoming WET.
Greenwich Mean Time
Greenwich Mean Time stays on GMT all year, so its offset from UTC never moves.
