Irkutsk Daylight Time (IRKST)

Introduction

Irkutsk Daylight Time (IRKST) was the daylight saving time observed in the Irkutsk region of Russia. It operated nine hours ahead of Coordinated Universal Time (UTC+09:00). The primary purpose of IRKST was to make better use of daylight during the longer days of summer by setting the clocks forward one hour.

Time Zone History

Irkutsk Daylight 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 the Irkutsk region of Russia was implemented intermittently but was eventually discontinued. Since then, the region has observed Irkutsk Standard Time (IRKT) year-round.
