Time in Chile

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]
