Guatemala observes Central Standard Time (UTC−6) year-round.
[1] Guatemala observed daylight saving time in four separate periods, setting the official time one hour forward: 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 Ministerio de Energía y Minas (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.
