MDT and EEST on the World Map
The map below highlights the MDT (Mountain Daylight Time) and EEST (Eastern European Summer Time) timezone regions across the globe.
MDT – Mountain Daylight Time
UTC-06:00Mountain Daylight Time (MDT) is the daylight saving offset in the Mountain Time Zone, 6 hours behind UTC.
- •MDT shares the same offset as CST (UTC-06:00).
- •Arizona does not switch to MDT, remaining on MST.
EEST – Eastern European Summer Time
UTC+03:00Eastern European Summer Time (EEST, UTC+03:00) is the daylight saving period across eastern Europe, from late March to late October.
- •EEST runs from the last Sunday in March to the last Sunday in October.
- •EEST is one hour ahead of Eastern European Time (EET, UTC+02:00).
- •During EEST, eastern Europe is level with Moscow, Istanbul and Riyadh.
- •EEST follows the EU-wide summer time schedule.
Understanding the +9h Gap: MDT vs EEST
MDT runs on Mountain Daylight Time (MDT) at UTC-06:00. EEST runs on Eastern European Summer Time (EEST) at UTC+03:00. That puts MDT 9 hours ahead of EEST — a difference of +9h at the current offsets.
In practice, when it is 9:00 AM in MDT it is 6:00 PM in EEST. Midnight in MDT is 9:00 AM in EEST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert MDT to EEST time
- Scheduling a call from MDT to EEST: a 10:00 AM start in MDT lands at 7:00 PM in EEST, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +9h gap: MDT and EEST 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 EEST is 6:00 PM in MDT.
- Coordinating a MDT-based team with EEST contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM MDT" is unambiguous; "3 PM" across a +9h gap is not.
- With a +9h gap there is no shared 9-to-5 window, so alternate the early start: one week MDT takes the early slot, the next week EEST does.
About MDT (Mountain Daylight Time)
Mountain Daylight Time (MDT) is observed during summer months in the Mountain Time Zone, except in Arizona which stays on MST year-round. MDT aligns with Central Standard Time (CST) at UTC-06:00.
About EEST (Eastern European Summer Time)
Eastern European Summer Time (EEST) is the daylight saving period used across eastern Europe, when clocks move one hour forward from Eastern European Time (EET, UTC+02:00) to UTC+03:00. It runs from the last Sunday in March to the last Sunday in October, in step with the rest of the European Union. EEST covers Greece, Finland, Romania, Bulgaria, the Baltic states, Ukraine and Moldova, and matches the offset used year-round by Moscow, Istanbul and Riyadh during those months. Athens and Helsinki both sit near the western edge of the EEST band, so summer evenings stay light well past 21:00.
Best time to call between MDT and EEST
With a +9h offset there is no overlap inside a normal 9 AM – 5 PM day. EEST opens at 9:00 AM EEST, which is 6:00 PM in MDT, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
MDT and EEST have no shared working hours because of the +9h gap. Teams need to alternate early starts or rely on asynchronous handovers.
MDT is 9 hours ahead of EEST (MDT UTC-06:00 → EEST 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.
