Introduction

Mexico

A new time zone, “Eastern Standard Time (Mexico),” was added in KB 3039024. It was originally set to observe DST from the first Sunday of April through the last Sunday of October. However, according to the latest announcement from the Mexican government, this time zone does not observe DST. Therefore, the previous DST rules for this time zone are removed in this update.

Mongolia

Mongolia will observe DST starting this year. DST for Mongolia starts on the last Saturday of March at 02:00 and ends on the last Saturday of September at 00:00. The following DST rules will be observed.

Time zone key nameDisplay nameDST startDST end
Mongolia Standard Time (UTC+8:00) UlaanbaatarLast Saturday of March at 02:00:00.000Last Saturday of September at 00:00:00.000
