CDT and MSK on the World Map
The map below highlights the CDT (Central Daylight Time) and MSK (Moscow Standard Time) timezone regions across the globe.
CDT – Central Daylight Time
UTC-05:00Central Daylight Time (CDT) is the daylight saving offset in the Central Time Zone, 5 hours behind UTC.
- •CDT is the same offset as EST (UTC-05:00), which can cause confusion.
- •CDT runs from the second Sunday in March to the first Sunday in November.
MSK – Moscow Standard Time
UTC+03:00Moscow Standard Time (MSK) is the time zone for Moscow and western Russia, 3 hours ahead of UTC.
- •All Russian train timetables use Moscow Time, regardless of location.
- •Russia abolished daylight saving time in 2011.
- •Moscow is the most populous city in Europe with over 12 million residents.
- •MSK shares the offset with Saudi Arabia (AST) and East Africa (EAT).
CDT vs MSK: Offsets, DST and Best Call Times
CDT runs on Central Daylight Time (CDT) at UTC-05:00. MSK runs on Moscow Standard Time (MSK) at UTC+03:00. That puts CDT 8 hours ahead of MSK — a difference of +8h at the current offsets.
In practice, when it is 9:00 AM in CDT it is 5:00 PM in MSK. Midnight in CDT is 8:00 AM in MSK. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert CDT to MSK time
- Scheduling a call from CDT to MSK: a 10:00 AM start in CDT lands at 6:00 PM in MSK, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +8h gap: CDT and MSK have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in MSK is 5:00 PM in CDT.
- Booking travel or deliveries: tracking MSK local time against CDT keeps pickup windows and arrival estimates honest across the +8h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM CDT" is unambiguous; "3 PM" across a +8h gap is not.
- With a +8h gap there is no shared 9-to-5 window, so alternate the early start: one week CDT takes the early slot, the next week MSK does.
About CDT (Central Daylight Time)
Central Daylight Time (CDT) is observed during summer months in the US and Canadian portions of the Central Time Zone. Clocks are moved forward by one hour, aligning with Eastern Standard Time (EST). Most of Mexico and Central America do not observe CDT, staying on CST year-round.
About MSK (Moscow Standard Time)
Moscow Standard Time (MSK) is the time zone used in Moscow, St. Petersburg, and much of western Russia. Russia abolished DST in 2011, so MSK is observed year-round. MSK is also the reference time for Russian railways – all train schedules in Russia are given in Moscow Time regardless of the actual local time zone.
Best time to call between CDT and MSK
With a +8h offset there is no overlap inside a normal 9 AM – 5 PM day. MSK opens at 9:00 AM MSK, which is 5:00 PM in CDT, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
CDT and MSK have no shared working hours because of the +8h gap. Teams need to alternate early starts or rely on asynchronous handovers.
CDT is 8 hours ahead of MSK (CDT UTC-05:00 → MSK UTC+03:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
