The clocks change twice a year moving from winter (standard) time to summer time and back. Find out when, and how Spain’s DST time relates to the rest of the world…

In 1996 the European Union (EU) standardised an EU-wide summertime, or Daylight Saving Time (DST).

The EU’s version of Daylight Savings runs from the last Sunday in Marchthrough to the last Sunday in October.

  • Clocks go forward by one hour in March
  • Clocks go back one hour in October

If dealing with other countries, it can be helpful to know how the different varieties of DST (for those countries that use the system) map on to each other. Most countries adjust their clocks at some time between midnight and 03:00; in the EU, clocks change at 01:00 Greenwich Mean Time (GMT).

Note: Many countries and territories change days of transitions to DST from year to year and some do not employ it every year.
