OMST — Omsk Standard Time
See OMST time details, UTC+6 offset, where it’s used, and compare it with other time zones for planning and conversion.
How to Convert OMST to Other Time Zones
Open the OMST converter page: Go to https://www.xconvert.com/time-converter/omst-time-zone to load the visual comparison grid with Omsk Standard Time (OMST, UTC+6) as the reference row. This page is useful when you need to line up working hours for eastern Russia with teams in Europe, Asia, or North America, such as scheduling an operations call, freight update, or software deployment window.
Add comparison cities with the “+ Add City” button: Click “+ Add City” and search for specific cities such as Moscow, Dubai, and Bangkok to compare OMST against major business and logistics hubs. Moscow is relevant for domestic coordination inside Russia, Dubai is common for trade and aviation links, and Bangkok is useful for regional Asia-Pacific scheduling because it shares nearby business-hour patterns but not always identical corporate calendars.
Drag across the grid to select a time range: Click “Select” if needed, then drag across the OMST row from 9:00 to 11:00 AM to highlight a purple meeting window and instantly see the equivalent times in the other rows. For example, 9:00 AM OMST is 6:00 AM in Moscow (UTC+3), 7:00 AM in Dubai (UTC+4), and 10:00 AM in Bangkok (UTC+7), which shows that an Omsk morning meeting is too early for western Russia but workable for Southeast Asia.
Export or share the selected time window: After selecting the range, use the export options shown on the page: ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is especially practical for remote teams and transport coordinators, because an ICS file or Google Calendar link lets everyone receive the meeting in their own local time automatically without manually recalculating from UTC+6.
About Omsk Standard Time (OMST)
Omsk Standard Time (OMST) is the time standard for the UTC+6:00 offset. It is exactly 6 hours ahead of Coordinated Universal Time, so when it is 12:00 noon UTC, it is 6:00 PM OMST.
OMST is associated with southwestern Siberia in Russia, especially the Omsk region, with Omsk as the best-known principal city. Omsk is a major Siberian urban center with a population of roughly 1.1 million people, located near the Irtysh River and serving as an industrial, transport, and administrative hub between the Ural region and deeper Siberia.
In practical scheduling terms, OMST is 3 hours ahead of Moscow Time (MSK, UTC+3), 2 hours ahead of Dubai (GST, UTC+4), and 1 hour behind Bangkok (ICT, UTC+7). That means when it is 9:00 AM in Omsk, it is 6:00 AM in Moscow, 7:00 AM in Dubai, and 10:00 AM in Bangkok, which matters for freight dispatch, regional procurement, and cross-border support coverage.
Several other time-zone abbreviations also use the UTC+6 offset, including ALMT, BST, BTT, F, IOT, KGT, QYZT, VOST, and YEKST, but they are not interchangeable in every context because they refer to different countries or administrative time systems. For accurate meeting planning, the offset may match while the place name, local workweek, and holiday calendar differ.
OMST and Daylight Saving Time
Omsk Standard Time does not observe daylight saving time. The current DST status is false, which means OMST remains at UTC+6 year-round and does not switch forward in spring or backward in autumn.
For the current year, 2026, OMST has no DST transition dates, no seasonal clock changes, and no alternate summer-time abbreviation. This makes OMST easier to work with than time zones in Europe or North America, because a meeting set for 3:00 PM OMST stays at UTC+6 in January, June, and November.
This fixed offset is especially useful for recurring coordination with regions that do change clocks. For example, OMST stays constant while London moves between UTC+0 and UTC+1 and New York moves between UTC-5 and UTC-4, so the time difference between Omsk and those cities changes seasonally even though Omsk itself never changes.
Frequently Asked Questions
What does OMST stand for?
OMST stands for Omsk Standard Time. It is the standard time designation used for the UTC+6:00 offset associated with the Omsk area of Russia and nearby administrative usage in southwestern Siberia.
Is OMST the same as GMT?
No, OMST is not the same as GMT. Greenwich Mean Time (GMT) is UTC+0, while Omsk Standard Time is UTC+6, so OMST is 6 hours ahead of GMT; when it is 8:00 AM GMT, it is 2:00 PM OMST.
Which cities use OMST?
The principal city most closely associated with OMST is Omsk, one of Russia’s largest Siberian cities. Omsk is an important rail, industry, and energy center, so OMST often appears in logistics schedules, domestic Russian coordination, and regional business operations tied to that part of Siberia.
What is the UTC offset for OMST?
The UTC offset for OMST is UTC+6:00. This means you add 6 hours to UTC to get local Omsk Standard Time, so 00:00 UTC becomes 06:00 OMST on the same calendar day.
When does OMST change?
OMST does not currently change seasonally because it does not observe daylight saving time. In 2026, there are no spring-forward or fall-back dates, so the offset remains UTC+6 for the entire year.
Is OMST the same as UTC+6?
In offset terms, yes, OMST corresponds to UTC+6. However, not every UTC+6 label means OMST specifically, because other abbreviations such as ALMT or BTT can share the same numeric offset while referring to different geographic regions and local naming conventions.
How far ahead is OMST from Moscow and UTC?
OMST is 6 hours ahead of UTC and 3 hours ahead of Moscow Time. So if it is 10:00 AM in Moscow, it is 1:00 PM in Omsk, which is important when arranging domestic Russian meetings across western and Siberian offices.
Does OMST have a daylight saving version?
No, there is no active daylight saving version of OMST in current use for 2026. The region stays on standard time all year, which reduces scheduling errors for recurring calls, transportation timetables, and system maintenance windows.
