When it is 12:00 UTC, it is 20:00 in Taipei. That offset never changes. Taipei uses UTC+8 permanently and does not observe daylight saving time in 2026 or 2027.

This offset is the same as China Standard Time (CST), Hong Kong Time (HKT), Singapore Time (SGT), Malaysia Time (MYT), Philippines Time (PHT), Indonesian Central Time (WITA), and Australian Western Standard Time (AWST). Each territory manages its own official time, but the wall clock shows the same hour and minute.

Which countries use UTC+8 year-round?

The following countries and territories use UTC+8 as their standard time for the entire country or territory. None of them observe daylight saving time.

Country / Territory IANA Zone
China Asia/Shanghai
Hong Kong Asia/Hong_Kong
Macau Asia/Macau
Malaysia Asia/Kuala_Lumpur, Asia/Kuching
Philippines Asia/Manila
Singapore Asia/Singapore
Taiwan Asia/Taipei
Western Australia (Australia) Australia/Perth

Parts of Indonesia and Mongolia also use UTC+8. See the section below.

Which major cities run on UTC+8?

These cities all share the same clock time as Taipei:

  • Taipei (Taiwan), Asia/Taipei
  • Beijing (China), Asia/Shanghai
  • Shanghai (China), Asia/Shanghai
  • Hong Kong (Hong Kong), Asia/Hong_Kong
  • Macau (Macau), Asia/Macau
  • Singapore (Singapore), Asia/Singapore
  • Kuala Lumpur (Malaysia), Asia/Kuala_Lumpur
  • Manila (Philippines), Asia/Manila
  • Makassar (Indonesia), Asia/Makassar
  • Perth (Australia), Australia/Perth
  • Ulaanbaatar (Mongolia), Asia/Ulaanbaatar (most of Mongolia uses UTC+8)

Why do Taiwan and China share an offset but not a time zone?

China uses a single time zone for the entire country: Beijing Time (UTC+8). That includes Xinjiang in the far west.

Taiwan and China share the same UTC offset but use separate IANA time zone identifiers: Asia/Taipei and Asia/Shanghai. The two zones are independent in the database. Software treats them as distinct even though the clocks match.

For practical purposes, a call between Taipei and Beijing works at the same local hour.

Which Southeast Asian UTC+8 countries matter for business?

Three of Taiwan's major trading partners in Southeast Asia share the same time zone.

Singapore and Malaysia both moved to UTC+8 in 1982. Singapore switched to match Malaysia for business and transport. Malaysia adopted the offset to align with its East Malaysian states (Sarawak and Sabah), which are geographically in UTC+8.

The Philippines has been on UTC+8 since 1936, with brief DST experiments. Manila is 15 hours ahead of New York in January and 12 hours ahead in July.

A call from Taipei to any of these cities is at the same local time. No calculation needed.

Does Perth share Taipei's time zone?

Western Australia uses Australian Western Standard Time (AWST), which is UTC+8, year-round. The state does not observe daylight saving time.

Perth is the largest city in this zone. In January, Perth is 3 hours behind Taipei. In July, Perth is 2 hours behind Taipei. The difference comes from Western Australia's standard time being the same year-round while Taipei stays on UTC+8.

Which parts of Indonesia use UTC+8?

Indonesia spans three time zones. The central zone, WITA (Waktu Indonesia Tengah), is UTC+8.

It covers: - Sulawesi (Makassar) - Lesser Sunda Islands (Bali, Lombok, Komodo) - North and South Kalimantan

The rest of Indonesia uses UTC+7 (Jakarta, Sumatra, Java) or UTC+9 (Maluku, Papua).

Is UTC+8 the same as GMT+8?

None for daily use. GMT (Greenwich Mean Time) and UTC (Coordinated Universal Time) are within a second of each other.

The technical difference: GMT is a time zone, UTC is a time standard. Most countries now define their time zones relative to UTC. The IANA database uses UTC offsets. If a website or device says "GMT+8", it means the same thing as UTC+8.

What are the business advantages of UTC+8?

Taiwan's four largest trading partners in the same time zone are China, Singapore, Malaysia, and the Philippines.

Same-time-zone trade means: - No scheduling friction for calls, video meetings, or deadlines. - Stock exchange hours overlap completely. The Taiwan Stock Exchange (TWSE) trades 09:00-13:30 local time. Singapore Exchange (SGX), Bursa Malaysia, and the Philippine Stock Exchange all operate within the same window. - Logistics and supply chains run on a single clock. A factory in Taipei and a warehouse in Shenzhen share the same working day.

The one-hour gap to Tokyo and Seoul is trivial. Japan and South Korea use UTC+9. A 09:00 meeting in Taipei is 10:00 in Tokyo. That is close enough for normal business.

The gap to Europe and the US is the real challenge. Taipei is 6-8 hours ahead of Western Europe and 12-16 hours ahead of US cities. But the same-offset zone covers 1.5 billion people across East and Southeast Asia. For regional business, UTC+8 is the most convenient time zone in the world.

How do I schedule across UTC+8 cities?

If you need to schedule a call between Taipei and any city in this list, you do not need a converter. The time is the same.

For cities outside UTC+8, use the time difference pages:
