US EditionWhy the Time Difference Between the US and Europe Will Be One Hour Shorter This Week
The one-hour shorter time difference lasts one week each autumn due to Europe and North America switching daylight saving time on different Sundays, affecting international scheduling.
- Sunday, the Atlantic time gap briefly shrinks by one hour as Europe and North America switch daylight saving time on different Sundays, disrupting international meetings for a week.
- Legal decisions and differing dates have produced the week-long mismatch, as Europe shifts at 2 a.m. on the last Sunday in October while the U.S. and Canada do so at 2 a.m. on the first Sunday in November, shaped by Congress.
- Historically, Europe adopted daylight saving during World War I, with Germany and Austria moving clocks in 1916, and European Union member states synchronized their switch dates from 2002.
- People organizing international meetings face missed calls, as lawmakers in the U.S. and Europe have proposed ending seasonal clock changes, but no reforms are finalized.
- Most countries do not observe daylight saving time, limiting any global standardization effort, and international coordination efforts have not succeeded, leaving the annual mismatch intact.
