Chile reintroduced Daylight Saving Time in 2016. Clocks change only in two time zonews: continental Chile (the offset or time difference goes from GMT-3 to GMT-4) and on Easter Island and Salas y Gomez Island (from GMT-5 to GMT-6).
There is no clock change announced for the third time zone which was set up in 2017 and covers the Magallanes Region.
The move back to DST was announced in May 2016, when the government decided that Standard Time would be revert to GMT-4, and Daylight Saving Time would start on 14 August 2016.
One year earlier, in 2015, the government had introduced a permanent DST offset, which meant GMT-3 throughout the year on continental Chile and GMT-5 on Easter Island.
Previously, the DST rule in Chile was from mid-October (First Sunday on or after 9 October) until mid-March (First Sunday on or after 9 March).
