The country with the most time zones is Russia. Due to its vast geographical expanse, Russia spans eleven time zones, from UTC+2 (Kaliningrad) to UTC+12 (Kamchatka). This wide range is necessary to accommodate the significant east-west distance across the country, making it the largest in the world by land area. Each time zone corresponds to a specific region, ensuring that local times align more closely with the position of the sun. The complexity of time zone management in Russia can be challenging, especially considering that some regions observe daylight saving time, while others do not.
