North Korea operates on Korea Standard Time (KST), which is 9 hours ahead of Coordinated Universal Time (UTC+9). The entire country follows the same timezone and does not observe daylight saving time.
Pyongyang, the capital, along with all other cities in North Korea follow KST. North Korea now shares the same timezone as South Korea and Japan after reverting from "Pyongyang Time" in 2018.
North Korea created its own timezone called "Pyongyang Time" (UTC+8:30) in 2015, exactly 70 years after liberation from Japan, as a symbol of independence. However, in 2018, as a goodwill gesture before the inter-Korean summit, North Korea returned to UTC+9 to match South Korea. This made North Korea the only country to have abandoned its own unique timezone in modern times.
