Central European Summer Time

Period of observation

Since 1996, European Summer Time has been observed between 01:00 UTC (02:00 CET and 03:00 CEST) on the last Sunday of March, and 01:00 UTC on the last Sunday of October; previously the rules were not uniform across the European Union.

There were proposals to abandon summer time in Europe from 2021, possibly by moving winter time up by an hour and keeping that time through the year.
