AST vs MSK: what's the time gap?
MSK is 7 hours ahead of AST. In everyday terms, once you know the time on one side you just add 7 hours to get the other — so a call between Halifax and Moscow is always 7 hours apart.
What time is it in MSK right now?
Right now the time in Moscow Standard Time (MSK) is Monday, June 29, 2026 · 8:53:57 PM. It ticks every second, so you’re always looking at the live MSK clock.
What time is it in AST right now?
And in Atlantic Standard Time (AST), it’s currently Monday, June 29, 2026 · 1:53:57 PM. Compare the two and the 7 hours gap is easy to see.
When is a good time to schedule a AST to MSK meeting?
For example, a 9:00 AM AST meeting takes place at 4:00 PM MSK. The trick is to aim for a slot that lands inside normal working hours on both sides. Once you’ve found a time, hit Share on the converter to copy a link with the time built in — easy to send to a colleague. Juggling three or more zones? The meeting planner highlights the hours that overlap for everyone.
How does daylight saving affect AST to MSK?
The labels AST and MSK are fixed offsets, so the result on this page is always exact. One side switches between standard and summer time while the other stays put, so the real-world gap can shift by an hour for part of the year. It's worth checking which label a region is actually using before you lock in a time.
Why can you trust this AST to MSK converter?
Every conversion here is calculated from the IANA time zone database — the same source your phone, computer, and browser rely on. Plenty of tools hard-code a single offset, which quietly goes wrong whenever a region changes its rules or flips for daylight saving. We follow the real rules instead, so AST to MSK stays accurate for today and for any past or future date you type in.

Frequently asked questions
How many hours ahead of AST is MSK?
MSK is 7 hours ahead of AST — a fixed 7 hours difference, since both are fixed-offset labels.
What time is it in MSK when it's 12:00 PM AST?
When it's 12:00 PM (noon) AST, it's 7:00 PM MSK.
Do AST or MSK use daylight saving time?
Atlantic Standard Time (AST) observes daylight saving, alternating with ADT; Moscow Standard Time (MSK) is a fixed offset with no daylight saving.
Why might the real-world AST–MSK difference change during the year?
The labels AST and MSK are fixed offsets, so this converter is always exact. But Atlantic Standard Time's region switches between standard and summer time, so for part of the year you may actually want ADT to MSK. Always check which label a region is currently using before you schedule.
