MSK — Moscow Standard Time

MSK is Moscow Standard Time, 3 hours ahead of UTC. It is a fixed offset: unlike a time zone, it does not change with the season — the zones that use it switch to a different abbreviation instead.

City clocks reflect whatever their zone is doing; where a city observes daylight saving time, its difference from MSK changes twice a year. Use the time zone converter for a specific date.

Why MSK is not an identifier

MSK is shorthand, not a standard. There is no registry of time zone abbreviations, no authority that assigns them, and nothing preventing two regions from adopting the same three letters — which is what makes codes like IST and CST unusable without context.

For anything a machine will read — a calendar invitation, a database column, an API response — use the IANA identifier of the zone (Europe/Moscow, for example) or an explicit UTC offset alongside the date. The identifier survives a change in the law; MSK and its 3 hours offset do not.

Frequently asked questions

What does MSK stand for?

MSK stands for Moscow Standard Time. It is 3 hours ahead of UTC, written UTC+3.

What is MSK in UTC?

Which time zone should I use instead of MSK?

Use an IANA identifier — Europe/Moscow for Moscow Standard Time — or state the UTC offset with the date. Abbreviations are not identifiers: they are not unique, they are not registered anywhere, and half of them change with the season. Calendar software resolves this automatically when you pick a city rather than typing letters.
