Asia/Phnom Penh Time Zone: Cambodia's Unchanging Clock
The Asia/Phnom Penh time zone covers the entire Kingdom of Cambodia, anchored by its capital Phnom Penh. It operates year-round at a fixed offset of UTC+07:00, with no daylight saving adjustments. This zone is shared by several Southeast Asian neighbors and a handful of territories across Asia and Antarctica, making it a key reference for regional coordination.
Zone Coverage and Users
Asia/Phnom Penh applies exclusively to Cambodia. The zone's standard offset is UTC+07:00, often referred to as Indochina Time (ICT) in the region. Other IANA zones at the same offset include Asia/Bangkok (Thailand), Asia/Ho_Chi_Minh (Vietnam), Asia/Vientiane (Laos), Asia/Jakarta and Asia/Pontianak (western Indonesia), as well as zones in Russia (Asia/Krasnoyarsk, Asia/Novosibirsk, etc.), Mongolia (Asia/Hovd), and Antarctica/Davis. This means that when it is noon in Phnom Penh, it is also noon in Bangkok, Ho Chi Minh City, Jakarta, and Krasnoyarsk.
Offset and Abbreviation
The offset UTC+07:00 means Phnom Penh is seven hours ahead of Coordinated Universal Time. The common abbreviation for this time zone in Cambodia is ICT (Indochina Time), though +07 is also used. Because the offset never changes, there is no seasonal shift in the abbreviation.
No Daylight Saving Time
Cambodia does not observe daylight saving time. The country has maintained a constant UTC+07:00 offset for decades. This means the sun's position relative to the clock remains nearly the same throughout the year: sunrise and sunset times shift only slightly due to the Earth's axial tilt, but the clock never jumps forward or back. For residents and travelers, this eliminates the biannual confusion of clock changes.
Major Cities and Countries
The primary city in this zone is Phnom Penh, with a population of over 2 million. Other significant Cambodian cities include Siem Reap (home to Angkor Wat), Battambang, and Sihanoukville. The zone also covers all of Cambodia's provinces. Outside Cambodia, the same offset is used by major cities such as Bangkok (Thailand), Ho Chi Minh City (Vietnam), Jakarta (Indonesia), and Novosibirsk (Russia).
Business Hours and Call Scheduling
For international coordination, Asia/Phnom Penh aligns with much of mainland Southeast Asia. Typical business hours (9:00 AM to 5:00 PM ICT) overlap well with East Asia: for example, 9 AM ICT is 10 AM in China (UTC+08:00) and 11 AM in Japan (UTC+09:00). For Europe, the overlap is limited: 9 AM ICT is 2 AM UTC (London winter) or 3 AM UTC+1 (summer). For North America, the time difference is large: 9 AM ICT is 9 PM Eastern Time (previous day) during US winter, and 10 PM during US summer. Best times for calls with US East Coast are early morning ICT (8-9 AM) corresponding to late evening US (8-9 PM previous day). With India (UTC+05:30), the 1.5-hour difference means 9 AM ICT is 7:30 AM IST, offering a good overlap for morning meetings.
Practical Guidance
When scheduling across zones, remember that Cambodia does not change clocks, so the time difference to countries that observe DST shifts twice a year. For example, during northern summer, Cambodia is 11 hours ahead of New York (EDT, UTC-04:00) and 6 hours behind Sydney (AEST, UTC+10:00). During winter, the difference to New York becomes 12 hours (EST, UTC-05:00). Always confirm the current offset of the other party, especially if they observe DST.
