What Time Zone Is Moscow In?
Moscow operates on Europe/Moscow, abbreviated as GMT+3, which is currently UTC+03:00 from Coordinated Universal Time. The IANA Time Zone Database (also known as the tz database or zoneinfo) records this under the identifier Europe/Moscow. That identifier is what your phone, laptop, and every major web service uses when they display a localized time for Moscow.
The designation Europe/Moscow follows the IANA convention of naming zones after the largest city in that timezone region. This naming is geographic, not political, it reflects where the zone is observed, not which government controls it. The full record for this zone, including historical UTC offsets and past DST rule changes, is publicly available in the Wikipedia list of tz database time zones.

Daylight Saving Time in Moscow
The DST indicator above shows whether Moscow currently observes Daylight Saving Time. When DST is active, clocks advance by one hour, shifting the UTC offset by +1 and changing the abbreviation (for example, from EST to EDT in New York). When DST ends, clocks fall back and the offset returns to its standard value.
Not all countries observe DST. Japan, China, India, most of Africa, and several other nations maintain a fixed offset year-round. Whether Europe/Moscow observes DST, and the exact dates of transitions, is governed by the rules stored in the IANA Time Zone Database , the same source your phone uses. The Wikipedia article on Daylight Saving Time provides a global map and country-by-country breakdown of DST observance.
Sunrise and Sunset in Moscow
Today in Moscow (55.8°N, 37.6°E), sunrise is approximately 07:19 and sunset is approximately 18:04 local time (Europe/Moscow). These times are calculated using the Spencer equation for solar declination and apply to today's date. Latitude significantly affects day length: cities near the equator see roughly 12 hours of daylight year-round, while high-latitude cities experience dramatic swings, midsummer days can exceed 20 hours near the Arctic Circle, while midwinter days shrink to under 4 hours. At 55.8° latitude, Moscow's day length varies substantially, expect notable differences between the longest and shortest days of the year.
Best Time to Call Moscow from Abroad
