Chile Summer Time (CLST)

Introduction

Chile Summer Time (CLST) is the daylight saving time observed in Chile. It operates three hours behind Coordinated Universal Time (UTC-03:00). The primary purpose of CLST is to make better use of daylight during the longer days of summer by setting the clocks forward one hour.

Time Zone History

Chile Summer Time was introduced to help conserve energy by reducing the need for artificial lighting in the evening hours. The practice of observing daylight saving time in Chile has been implemented and discontinued several times throughout history, with the most recent changes occurring in the early 21st century. The current system of starting CLST on the first Saturday in September and ending it on the first Saturday in April was standardized to align with energy conservation efforts.
