Asian Time Zones
A complete guide to time zones across all 49 countries of Asia — UTC offsets, live clocks, DST schedules, history, and practical time differences.
Overview: Time in Asia
Asia is the world's largest continent — spanning over 9,600 km from west to east, from Turkey's western coast on the Bosphorus to the eastern tip of Russia's Chukotka Peninsula near Alaska. This extraordinary longitudinal range produces the world's widest continental time zone span: from UTC+2 (Israel, Jordan, Lebanon) in the west to UTC+12 (Kamchatka, Russia) in the east — a ten-hour spread, with UTC+5:30 (India) and UTC+5:45 (Nepal) adding half-hour and quarter-hour irregularities found nowhere else on Earth.
Unlike Europe, Asia has no continental DST coordination. The continent's 49 sovereign states and territories each manage their own time policies independently. The vast majority — including China, Japan, South Korea, India, and all of Southeast Asia — observe no daylight saving time whatsoever. A small number of countries in the Levant do shift clocks seasonally: Israel, Lebanon, Syria, Iran, and the Palestinian Territories all observe DST, though on differing schedules. Jordan permanently abolished DST in 2022 and is now UTC+3 year-round.
Asia also hosts some of the world's most unusual timekeeping decisions: China enforces a single UTC+8 time zone across a territory spanning over 60 degrees of longitude — meaning sunrise in Xinjiang can fall after 10:00 local time in winter. India and Sri Lanka use UTC+5:30, Nepal uniquely uses UTC+5:45, and several Middle Eastern countries shifted their clocks permanently to avoid calendar conflicts with Friday prayers.

Asia's Major Time Zones by Region
Asia's time zones are best understood by geographic sub-region. The green chips show the currently active offset, computed live from your browser clock.
Middle East UTC+2 to UTC+4
The western edge of Asia. Israel uses IST (UTC+2), advancing to IDT (UTC+3) during summer DST. Lebanon, Syria, and the Palestinian Territories also observe UTC+2/+3 DST cycles. Jordan permanently abolished DST in February 2022 and now uses AST (UTC+3) year-round. Turkey uses TRT (UTC+3) permanently since September 2016. Saudi Arabia, UAE, Oman, Qatar, Bahrain, Kuwait, Yemen, and Iraq all use fixed UTC+3 year-round. Iran uniquely uses IRST (UTC+3:30) in winter, advancing to IRDT (UTC+4:30) during its own DST cycle.
South Asia UTC+5 to UTC+6
South Asia uses fixed, non-integer offsets. Pakistan uses PKT (UTC+5). India and Sri Lanka share IST (UTC+5:30) — the most-used non-integer offset on Earth, covering over 1.4 billion people. Nepal uses NPT (UTC+5:45) — the only UTC+5:45 zone in the world, a deliberate 15-minute separation from India. Bangladesh uses BST (UTC+6). None of these countries observe DST.
Central Asia UTC+5 to UTC+6
The five former Soviet republics use fixed UTC offsets with no DST. Kazakhstan unified to a single national time zone — UTC+5 — across the entire country in March 2024, ending the previous two-zone system. Uzbekistan, Tajikistan, and Turkmenistan use UTC+5; Kyrgyzstan uses UTC+6.
East Asia UTC+8 to UTC+9
Home to the world's most populous countries. China uses a single national time zone — CST (UTC+8) — across all its territory, including Xinjiang which lies at a natural UTC+6 longitude. Japan uses JST (UTC+9), South Korea uses KST (UTC+9), North Korea uses KST (UTC+9) — North Korea briefly used UTC+8:30 from 2015 to 2018 before re-aligning with South Korea. Taiwan and Hong Kong use CST (UTC+8). Mongolia uses UTC+8 in most provinces (UTC+7 in two western provinces). None of these countries observe DST.
Southeast Asia UTC+6:30 to UTC+9
Southeast Asia uses fixed offsets throughout — no country in the region observes DST. Myanmar uniquely uses MMT (UTC+6:30). Thailand, Cambodia, Laos, and Vietnam all use ICT (UTC+7). Malaysia, Singapore, Brunei, and the Philippines use UTC+8. Indonesia spans three time zones: WIB (UTC+7), WITA (UTC+8), and WIT (UTC+9).
Russia (Asian) UTC+5 to UTC+12
Asian Russia spans from Yekaterinburg (UTC+5) to Kamchatka and Chukotka (UTC+12), covering seven time zones. Russia abolished DST across all its territory in October 2014. All Russian zones are now permanently fixed.
All Asian Countries, Capitals & UTC Offsets
All 49 widely recognised Asian countries and territories. The Active Now column shows each country's live current UTC offset, computed from your browser's real-time clock and updated every minute. For multi-zone countries (Russia, Kazakhstan, Indonesia), the representative capital city zone is shown. Full global coverage: GMT/UTC Countries · World Time Zones List.
| Country | Capital | Standard (Winter) | Summer (DST) | Active Now | IANA Zone | DST? |
|---|
* "Active Now" is computed via Intl.DateTimeFormat using each country's IANA timezone identifier — updated every minute. The vast majority of Asian countries do not observe DST. Countries marked "Yes" shift clocks seasonally; their DST schedules vary by country and do not follow a unified continental system. Non-integer offsets (UTC+3:30, UTC+4:30, UTC+5:30, UTC+5:45, UTC+6:30) are displayed exactly as returned by the browser's timezone data.

Daylight Saving Time in Asia
Unlike Europe or North America, Asia has no continental DST coordination. The overwhelming majority of Asian countries — including the continent's most populous nations (China, India, Japan, Indonesia, Bangladesh, Pakistan) — do not observe DST at all. Learn more in the full Daylight Saving Time guide.
The countries that do observe seasonal clock changes are concentrated primarily in the Levant and western Middle East. As of 2022, Jordan permanently abolished DST (now UTC+3 fixed). The remaining DST countries each follow their own independent schedule:
Israel — IDT
Israel uses IST (UTC+2) in winter, advancing to IDT (UTC+3) in summer. The exact dates are set annually by the Israeli government — typically springing forward on the last Friday before April 2 and falling back in late October. The dates differ from the European schedule.
Jordan — AST (Fixed)
Jordan permanently abolished DST on February 2, 2022, and now uses AST (Arabia Standard Time, UTC+3) year-round. Before 2022, Jordan observed UTC+2/+3 seasonal changes aligned roughly with the EU schedule. The change was made for economic continuity and energy reasons. Jordan is now among the permanently UTC+3 countries alongside Saudi Arabia, Iraq, and Kuwait.
Lebanon — EEST
Lebanon uses EET (UTC+2) in winter and EEST (UTC+3) in summer. Clock changes follow the last Sunday of March and last Sunday of October — the same calendar dates as EU countries.
Syria — EEST
Syria uses EET (UTC+2) in winter and EEST (UTC+3) in summer. The last Friday of March and last Friday of October are the nominal transition dates, though implementation has been inconsistent in recent years.
Iran — IRDT
Iran uses IRST (UTC+3:30) in winter, advancing to IRDT (UTC+4:30) in summer. Iran's clock change is tied to the Persian calendar — clocks spring forward at the Spring Equinox (around March 21, Nowruz) and fall back at the end of Shahrivar (around September 22). This is independent of the Gregorian calendar.
Palestinian Territories — EEST
Gaza and the West Bank use EET (UTC+2) in winter and EEST (UTC+3) in summer. The Palestinian Authority sets its own DST dates, which have historically been the last Sunday of March and last Sunday of October, though dates may vary.

History of Asian Time Zones
Before colonial standardisation, Asian cities operated on diverse local solar times. The transition to standard time zones was largely driven by European colonial administrations, telegraph networks, and — in Japan's case — a deliberate embrace of Western industrial timekeeping as part of the Meiji modernisation.
Japan introduces railway time on the Tokyo–Yokohama line, the country's first railway. The Meiji government officially adopts the Western (Gregorian) calendar and a unified national standard time in 1873, aligning Japan with international commercial networks.
The International Meridian Conference in Washington D.C. designates Greenwich as the global Prime Meridian. Asia's future time zones would be anchored to multiples of ±1 hour east of this point — though many Asian governments would later deviate from this model.
India, under British colonial administration, adopts a unified standard time of UTC+5:30 — a compromise between the natural solar times of Calcutta (UTC+5:54) and Bombay (UTC+4:51). The non-integer offset persists to this day.
The People's Republic of China, following the revolution, collapses five Republican-era time zones into a single national zone — Beijing Standard Time (CST, UTC+8). This remains one of the world's most contested timekeeping decisions, with residents of Xinjiang (UTC+6 by solar position) effectively using an unofficial local time alongside the official national one.
Japan, South Korea, and Taiwan each discontinue wartime or occupation-era DST schedules and settle on fixed standard times. Japan standardises at JST (UTC+9), South Korea at KST (UTC+9), and Taiwan at CST (UTC+8). None have observed DST since.
China observes DST from 1986 onward, having introduced it that year as part of energy-saving reforms. The last DST year is 1991; from spring 1992, UTC+8 is confirmed permanently as the sole national standard, with no spring-forward. China was the last major East Asian economy to abandon DST.
Following the dissolution of the Soviet Union, the five Central Asian republics establish independent time zones. Most adopt UTC+5 or UTC+6 and, within a few years, abandon DST entirely — prioritising economic alignment with Russia and continuity of agricultural schedules.
North Korea briefly shifts from KST (UTC+9) to Pyongyang Time (UTC+8:30) in August 2015, officially distancing itself from the Japanese colonial standard. In May 2018, ahead of the inter-Korean summit, North Korea reverts to UTC+9 to align with South Korea.
Turkey abandons DST permanently in September 2016, fixing clocks at UTC+3 year-round — one hour ahead of where its longitude would place it. The government cited business continuity and agricultural scheduling as primary reasons.
Asia's timekeeping landscape remains the most diverse and fragmented of any continent. Kazakhstan unified to a single national UTC+5 zone in March 2024. Iran's DST system, tied to the Persian calendar, remains unique globally. Use the interactive Time Zone Map and Time Zone Converter for current offsets.
Geography & Time Zone Anomalies
Asia's time zone map is shaped as much by political decisions as by geography. Several of the world's most notable timekeeping anomalies are found here.
China: One Zone for 60° of Longitude
China spans roughly 5,000 km east to west — similar to continental Europe — yet uses a single time zone (UTC+8). Solar noon in Kashgar, Xinjiang falls around 14:30 clock time in winter. Many Uyghur residents informally observe "Xinjiang time" (UTC+6), two hours behind Beijing. The gap between China's eastern and western solar noon is over 3.5 hours.
India: UTC+5:30 — The World's Most Used Half-Hour Offset
India's UTC+5:30 offset covers over 1.4 billion people — far more than any other non-integer time zone. The half-hour compromise was chosen under British rule to split the difference between Calcutta and Bombay solar times. There is periodic political discussion about dividing India into two time zones (east and west), but no change has been legislated.
Nepal: The Only UTC+5:45 in the World
Nepal uses UTC+5:45 — the world's only quarter-hour offset from a full hour. It was introduced to create a deliberate 15-minute separation from India (UTC+5:30), asserting Nepal's distinct national identity. Solar noon in Kathmandu aligns closely with the 5:45 offset.
Iran: UTC+3:30 and a Persian-Calendar DST
Iran's UTC+3:30 standard time is geographically appropriate for Tehran (longitude ~51°E, natural solar offset ~+3:24). Iran's DST uniquely follows the Persian solar calendar — the spring-forward occurs at Nowruz (Persian New Year, Spring Equinox, ~March 21) and the fall-back at the end of summer (~September 22). This makes Iran the only country whose DST dates shift relative to the Gregorian calendar each year.
Singapore: UTC+8, Though Longitude is UTC+7
Singapore sits at longitude 103°E, which places its solar noon at approximately UTC+6:52. Singapore uses UTC+8 — a full hour and eight minutes ahead of its solar time. This reflects its economic integration with Hong Kong, Taiwan, and Malaysia (which uses UTC+8 for historical reasons rooted in its eastern peninsula's geography).
Myanmar: UTC+6:30 — One of Two Half-Hour Zones in the Region
Myanmar (Burma) uses MMT (UTC+6:30), placing it between India (UTC+5:30) and Thailand (UTC+7). The offset reflects an intentional distancing from both neighbours. Myanmar and India are the two largest countries in the region to use non-integer offsets, together covering a significant portion of South and Southeast Asia's population.
Interesting Facts & Curiosities
Russia spans more time zones than any other country
Russia stretches from UTC+2 (Kaliningrad, Europe) to UTC+12 (Kamchatka, Pacific), covering 11 time zones. Its Asian portion alone spans from UTC+5 (Yekaterinburg) to UTC+12. Flying from Moscow to Vladivostok is a 9-hour journey that crosses 7 time zones — the equivalent of flying from London to Denver.
UTC+5:30 serves more people than any other non-integer offset
India and Sri Lanka share IST (UTC+5:30), covering a combined population of over 1.44 billion. For comparison, the second-most-used non-integer offset — Iran's UTC+3:30 — covers around 90 million people. UTC+5:30 is the most-used time zone on Earth by population after UTC+8 (China alone: 1.4 billion) and UTC+5:30 itself.
Xinjiang's unofficial dual-time system
China officially uses UTC+8 across all its territory. But in Xinjiang, many Uyghur and other non-Han residents informally observe "Xinjiang time" (UTC+6), two hours behind Beijing. Government offices, Chinese state media, and Han Chinese residents use UTC+8. This means daily life effectively operates on two parallel clocks — a situation with no equivalent anywhere else on Earth.
The Gulf DST question and prayer times
Saudi Arabia, UAE, Bahrain, Kuwait, Qatar, and Oman have never observed DST. One practical reason is that DST would shift Fajr (dawn prayer) time relative to sunrise in ways that complicate worship schedules — particularly in summer, when prayer times are already condensed. Maintaining fixed offsets provides predictability for the five daily prayers throughout the year.
North Korea's time zone U-turn
In 2015, North Korea created "Pyongyang Time" at UTC+8:30 — exactly 30 minutes behind South Korea and Japan — citing the need to undo a "clock robbery" imposed by Japanese colonial rule. Just three years later, in May 2018, North Korea reversed the change and returned to UTC+9 ahead of a historic inter-Korean summit, aligning clocks with Seoul for the first time in three years.
Asia–Europe time difference: how wide is it?
From western Turkey (UTC+3, no DST) to Tokyo (UTC+9), the spread is 6 hours. From the westernmost point of continental Asia (Turkey's European side at UTC+3) to Kamchatka (UTC+12), the gap is 9 hours. Compare with European Time Zones (max 5 hours, including Azores) or North America (max 6 hours for the contiguous 48 states).
Practical Examples & Time Differences
Use our Time Zone Converter for real-time calculations. Examples below use standard (fixed) offsets. Countries with DST (Israel, Lebanon, Syria, Iran, Palestinian Territories) will have different differences during summer months. Note: Jordan is now UTC+3 fixed year-round (DST abolished Feb 2022).
🕐 Dubai → Tokyo
UAE (UTC+4) vs Japan (UTC+9)
Tokyo is always 5 hours ahead of Dubai. When it's 09:00 in Dubai, it's 14:00 in Tokyo. Both use fixed offsets — the gap never changes across the year.
🕐 Mumbai → Singapore
India (UTC+5:30) vs Singapore (UTC+8)
Singapore is always 2.5 hours ahead of Mumbai. When it's 09:00 in Mumbai, it's 11:30 in Singapore. Neither country observes DST.
🕐 London → Delhi
UK (UTC+0/+1 DST) vs India (UTC+5:30)
In winter (UK on GMT), India is 5h 30min ahead. In summer (UK on BST UTC+1), India is only 4h 30min ahead. India's offset never changes; the gap shifts because the UK observes DST.
🕐 New York → Beijing
USA EST (UTC−5/−4 DST) vs China (UTC+8)
When New York is on EST (winter), Beijing is 13 hours ahead. When New York is on EDT (summer), the gap narrows to 12 hours. China never changes; New York's DST creates the shift.
🕐 Tel Aviv → Seoul
Israel (UTC+2/+3 DST) vs South Korea (UTC+9)
In winter, Seoul is 7 hours ahead of Tel Aviv. During Israeli DST (spring–autumn), the gap narrows to 6 hours. Korea uses a fixed UTC+9 year-round.
🕐 Tehran → Bangkok
Iran (UTC+3:30/+4:30 DST) vs Thailand (UTC+7)
In Iranian winter (IRST UTC+3:30), Bangkok is 3h 30min ahead. During Iranian summer (IRDT UTC+4:30), the gap narrows to 2h 30min. Thailand never changes clocks.
