What time is AEST when it is 12:00 MSK?
20:00. Australian Eastern Time is 8 hours ahead of Moscow Time in January and 7 hours ahead of it in July. The gap moves because Sydney observes daylight saving and Moscow does not, so the difference between them is not a fixed number. There is no hour of the standard working day that is inside 9-to-5 in both Moscow and Sydney. One side has to take the call outside office hours, so it is worth agreeing which.
Is the difference between MSK and AEST the same all year?
No, and this is the pair where that matters. Australian Eastern Time is 8 hours ahead of Moscow Time in January and 7 hours ahead of it in July. The gap moves because Sydney observes daylight saving and Moscow does not, so the difference between them is not a fixed number. Booking a recurring call across these two and assuming one number will drift by an hour twice a year — check the date, not just the zones.
What do MSK and AEST actually stand for?
MSK is Moscow Time, the zone covering Moscow, currently UTC+3 in January. AEST is Australian Eastern Time, covering Sydney, at UTC+11. Russia abolished daylight saving in 2014, so Moscow is a fixed UTC+3 all year. Its distance from Europe therefore changes twice a year — two hours from Paris in winter, one in summer — even though Moscow itself never moves.
Anything worth knowing about Australian Eastern Time?
Southern hemisphere daylight saving runs October to April — the opposite half of the year to Europe and North America. So the gap between Sydney and London swings by two hours across the year, not one.
When is a good time to call between Moscow and Sydney?
There is no hour of the standard working day that is inside 9-to-5 in both Moscow and Sydney. One side has to take the call outside office hours, so it is worth agreeing which. If the call has to happen outside that, the fairer arrangement is usually to alternate which side takes the awkward hour rather than always asking the same one.

The difference, and whether you can rely on it
In January, Australian Eastern Time is 8 hours ahead of Moscow Time — UTC+3 against UTC+11. In July it is 7 hours ahead instead. That is the part worth carrying away: this is not a pair you can memorise a single number for.
Why the gap moves
Sydney observes daylight saving; Moscow does not. So the clocks in one city move twice a year while the other stays put, and the distance between them changes with them. Any calculation you did in one season is wrong in the other. The converter above uses the date you give it rather than today’s offset, which is the only way to get a future meeting right when it falls on the other side of a changeover.
When you can both be at a desk
There is no hour inside 9-to-5 in both Moscow and Sydney. Whatever you schedule, one side is taking it outside working hours — so the useful question is not when to meet but who absorbs the inconvenience, and whether it alternates.
Reading the abbreviations literally will mislead you
MSK strictly means one fixed offset, but almost nobody uses it that way. People write it to mean the time in Moscow, which shifts if the city observes daylight saving, which this one does not. This page follows the common usage rather than the strict one, because the strict reading gives an answer that is wrong for a good part of the year.
Russia abolished daylight saving in 2014, so Moscow is a fixed UTC+3 all year. Its distance from Europe therefore changes twice a year — two hours from Paris in winter, one in summer — even though Moscow itself never moves. Southern hemisphere daylight saving runs October to April — the opposite half of the year to Europe and North America. So the gap between Sydney and London swings by two hours across the year, not one.
Scheduling something recurring
For a one-off, the converter above is the whole job. For a standing meeting across these two zones, where the gap changes, it is worth putting the invitation in a calendar that stores the zone rather than the time — then the changeover is handled for you and nobody has to remember. If you are trying to find a slot across more than two places at once, the meeting planner shows a whole day at a glance instead.
