Time in Guatemala
Guatemala observes Central Standard Time (UTC−6) year-round. Daylight saving time 
Guatemala observed daylight saving time in four separate periods, setting the official time one hour forward:
 from November 25, 1973 to February 24, 1974
 from May 21 to September 22, 1983
 from March 23 to September 7, 1991
 from April 30 to October 1, 2006
The clock change in 1973 was made in response to the 1970s energy crisis. The clock change in 2006 was intended to reduce the consumers' spending on energy bills. While Guatemala observed five months of daylight saving time in 2006, according to the  (MEM), nationwide energy consumption was reduced by 36 million kilowatt-hours, equivalent to monetary savings of Q64 million. Guatemala intended to observe daylight saving time the following year, but the plan never came through. IANA time zone database
