How Does Daylight Saving Time Affect Central European Time?

CET (UTC+1) switches to CEST (UTC+2) during DST, affecting most of continental Europe.

The Switch

PeriodAbbreviationUTC Offset
Oct (last Sun) - Mar (last Sun)CETUTC+1
Mar (last Sun) - Oct (last Sun)CESTUTC+2
2026 dates:
  • March 29, 2026: CET to CEST
  • October 25, 2026: CEST to CET

Countries Affected

Germany, France, Italy, Spain, Netherlands, Belgium, Austria, Switzerland, Poland, Czech Republic, Slovakia, Hungary, Croatia, Serbia, Norway, Sweden, Denmark, and more.

Impact on Scheduling

  • CET/CEST vs New York: 6 hours apart year-round (both shift together)
  • CET vs India (IST): 4.5h in winter, 3.5h in summer
  • CET vs Tokyo (JST): 8h in winter, 7h in summer

Quick Answer

CET (UTC+1) switches to CEST (UTC+2) on the last Sunday of March, back on the last Sunday of October. The gap with the US stays the same; the gap with Asia shrinks by 1 hour in summer.
