Daylight Saving Time–First Half of 1973
Daylight Saving Time (DST) 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 showing the countries and territories which observed DST during the first half of 1973.
Current country/territory names, rather than historic country names are displayed, so the list could contain countries that did not exist at the time.
Also, please see the page for the second half of 1973 or the overview over start and end times for 1973 sorted by country.
