Daylight Saving Time Around the World 2015

Daylight saving time is often incorrectly referred to as “daylight savings time”. In some countries, it is also called “summer time”. When DST is not observed, it is called standard time, normal time or winter time.

This list displays a brief (but not complete) overview over which countries and territories that observed DST during 2015.

Current country/territory names, rather than historic country names are displayed, so the list could contain countries that did not exist at the time.

Detailed information is available for the first half of 2015 and the second half of 2015.
