Current time across all major time zones worldwide. All clocks update live every second.
UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. It never changes — no DST, no seasonal shifts. GMT (Greenwich Mean Time) is essentially the same as UTC for practical purposes, though GMT is based on Earth rotation while UTC uses atomic clocks.
In the Americas, EST (Eastern Standard Time) is UTC−5, CST is UTC−6, MST is UTC−7, and PST is UTC−8. During Daylight Saving Time, these shift forward by one hour: EDT (UTC−4), CDT (UTC−5), MDT (UTC−6), and PDT (UTC−7). Not all US states observe DST — Arizona and Hawaii stay on standard time year-round.
In Europe, CET (Central European Time) is UTC+1, EET is UTC+2, and MSK (Moscow) is UTC+3. Most of Europe observes DST, shifting to CEST (UTC+2) and EEST (UTC+3) in summer. Russia stopped observing DST in 2011, so MSK remains UTC+3 year-round.
In Asia, IST (India Standard Time) is UTC+5:30 — India does not observe DST. JST (Japan Standard Time) and KST (Korea Standard Time) are both UTC+9, and neither country observes DST. AEST (Australian Eastern Standard Time) is UTC+10, shifting to AEDT (UTC+11) during DST. NZST (New Zealand Standard Time) is UTC+12, shifting to NZDT (UTC+13) in summer.

The current UTC time is shown at the top of this page in the large clock. UTC is the global reference time and never changes with Daylight Saving Time. All other time zones are calculated as offsets from UTC.
For most practical purposes, UTC and GMT are the same time. GMT is based on the Earth's rotation, while UTC is based on atomic clocks. UTC is more precise and is the modern standard used in computing, aviation, and international communications. GMT is still commonly used in the UK.
No. UTC never changes — it is constant year-round. Only local time zones observe DST. When a country switches to DST, its offset from UTC changes by one hour (e.g., EST UTC−5 becomes EDT UTC−4), but UTC itself remains unchanged.
Most countries near the equator do not observe DST because daylight hours are consistent year-round. Major countries without DST include: India, Japan, China, Singapore, most of Africa, most of Southeast Asia, Russia, and parts of Australia (Queensland, Northern Territory, Western Australia). The US states of Arizona and Hawaii also do not observe DST.
There are 24 primary time zones (one per hour), but due to political boundaries and half-hour/quarter-hour offsets, there are approximately 38–40 distinct time zones in use worldwide. Some countries span multiple zones (Russia has 11, the USA has 6, Canada has 6).
