Time in Chile is divided into two time zones. Continental Chile uses two time zones, Chile Standard Time (CLT, UTC-4) and Chile Summer Time (CLST, UTC-3). Additionally, Easter Island uses Easter Island Standard Time (EAST, UTC-6) and Easter Island Summer Time (EASST, UTC-5).[1]

In 2013, Chile moved from CLST to CLT on April 27, and moved back to CLST on September 7.

In mainland Chile Time is changed at 24:00 on a Saturday, i.e. at 0:00 on the following Sunday. In Easter Island time is changed at 20:00 on a Saturday.[2]

In 1903, another official time was operating in Coquimbo. It was synchronized at -4 hours, 45 minutes 20.7 seconds with respect to GMT.[2]

In January 10, 1910, Chile adopted GMT-5 as its official time.[2]

On July 1, 1919, time was set as 4 hours 42 minutes 46.3 seconds behind Greenwich.[2]

On January 28, 2015, Chile adopted definitively UTC–3 as its official time and UTC–5 for Easter Island.[3]
