Why Moscow is 8 hours ahead in winter and 7 in summer
Moscow Standard Time (MSK) sits at UTC+3. Russia abolished daylight saving time in October 2014, so that offset holds firm every month of the year.
New York swings between Eastern Standard Time (EST, UTC-5) and Eastern Daylight Time (EDT, UTC-4). The clock moves twice a year: forward on the second Sunday of March, back on the first Sunday of November. Moscow stays put. The gap shrinks and grows around it.
On 15 January 2026, Moscow is 8 hours ahead. A 09:00 MSK start is 01:00 EST. On 15 July 2026, Moscow is 7 hours ahead. That same 09:00 MSK becomes 02:00 EDT. Summer softens the mismatch by one hour.
When do Moscow and New York business hours overlap?
Moscow's business day runs 09:00 to 18:00 MSK. New York's runs 09:00 to 17:00 EST or EDT. The overlap is a sliver.
| Moscow time | New York time (EST) | New York time (EDT) |
|---|---|---|
| 08:00 | 00:00 | 01:00 |
| 09:00 | 01:00 | 02:00 |
| 10:00 | 02:00 | 03:00 |
| 11:00 | 03:00 | 04:00 |
| 12:00 | 04:00 | 05:00 |
| 13:00 | 05:00 | 06:00 |
| 14:00 | 06:00 | 07:00 |
| 15:00 | 07:00 | 08:00 |
| 16:00 | 08:00 | 09:00 |
| 17:00 | 09:00 | 10:00 |
| 18:00 | 10:00 | 11:00 |
To get both sides in daylight hours, someone compromises. Push the Moscow participant to 08:00 or 09:00 MSK. The New York participant dials in at 00:00 or 01:00 EST, or 02:00 or 03:00 EDT. That is late night. The alternative: Moscow stays late, New York starts early.
What time should I call Moscow from New York?
Book the call for 08:00 to 10:00 New York time. That lands at 15:00 to 17:00 MSK in winter or 16:00 to 18:00 MSK in summer. You catch the tail of the Moscow workday.
For a Moscow morning call, dial from New York between 00:00 and 02:00 EST (01:00 and 03:00 EDT). That is a late-night call, not a business-hours solution. Do not schedule it unless the New York side agrees explicitly.
Personal calls between family and friends work better in the opposite direction. A Moscow evening call at 20:00 MSK is 12:00 EST in winter or 13:00 EDT in summer. A New York lunchtime chat. A New York evening call at 20:00 EST hits Moscow at 04:00 the next morning. Unworkable.
Skip the common advice to "find a middle ground." There is no comfortable middle ground. Pick one side to absorb the inconvenience and rotate it if the calls are regular.
How to convert Moscow and New York time without a tool
For a fast mental conversion in winter, add 8 hours to New York time to get Moscow time. In summer, add 7 hours. Subtract to go the other way.
Enter a time in either city in the converter and it shows the equivalent in the other, accounting for EST or EDT.
If you are flying between the two cities, check the jet lag guide for recovery strategies. Westbound travel, Moscow to New York, gains hours and adjusts easier. Eastbound travel, New York to Moscow, loses 7 or 8 hours and hits harder. On arrival, adopt the local schedule immediately. Light exposure matters.
Moscow Exchange hours for New York traders
The Moscow Exchange main session runs 10:00 to 18:45 MSK. That is 02:00 to 10:45 EST in winter, 03:00 to 11:45 EDT in summer.
New York traders can catch the last hour of Moscow trading before their own market opens at 09:30 ET. In winter, the overlap is slightly wider. In summer, the Moscow close at 11:45 EDT leaves a narrow window before the New York lunch lull.
Do not rely on outdated calendar apps. Some systems still apply automatic DST to Moscow. Manually set Moscow to UTC+3 and verify against a live converter. The Moscow Time FAQ covers common app errors.
