How to Check Current Time in Siem Reap, Cambodia

1. Open the Siem Reap time converter page: Go to https://www.xconvert.com/time-converter/cambodia/siem-reap. The page loads with Siem Reap pre-selected on the comparison grid in the Cambodia time zone, which is useful if you're planning a hotel check-in near Angkor Wat, confirming a tour pickup, or scheduling a call with a travel operator in northwestern Cambodia.

2. Add the cities you want to compare: Click + Add City and search for places such as New York, London, or Bangkok. These are practical comparisons for tourism, NGO coordination, and hospitality operations because Siem Reap works frequently with visitors from the US and UK, while Bangkok is a major regional aviation hub with many onward connections to Cambodia.

3. Drag across the grid to select a meeting window: Use the Select button if needed, then drag on Siem Reap’s 24-hour timeline to highlight a time range in purple, such as 9:00 AM to 11:00 AM. On a standard date, that window in Siem Reap corresponds to 8:00 PM to 10:00 PM in New York during EST or 9:00 PM to 11:00 PM during EDT, showing why a morning call in Cambodia often lands the previous evening in the US.

4. Export or share the selected time: After selecting the range, use the export options shown on the page: ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is especially helpful for sending a confirmed tour briefing, remote team check-in, or supplier call so everyone sees the appointment in their own local time without manually converting UTC+7.

About Siem Reap Time Zone

Siem Reap uses the IANA time zone Asia/Phnom_Penh, which is the standard time zone used across Cambodia. The city operates on UTC+7 year-round, the same offset as Phnom Penh, the national capital, and other major Cambodian locations. Because Siem Reap is in northwestern Cambodia near the Thai border, this time setting is important for travelers coordinating overland routes, domestic flights, and regional business schedules.

Cambodia does not observe daylight saving time, so Siem Reap stays on UTC+7 in every month of the year. There are no seasonal clock changes in March, October, or November, unlike cities in Europe, North America, or Australia. That makes scheduling more predictable for hotels, tour companies, and remote teams, but the time difference with places like London, New York, and Sydney changes seasonally because those locations may switch in and out of DST.

Regionally, Siem Reap shares the same UTC+7 offset with Bangkok and Ho Chi Minh City, which simplifies coordination with Thailand and Vietnam. It is 1 hour behind Singapore and Kuala Lumpur (UTC+8) and 2 hours behind Tokyo (UTC+9). This matters for airline itineraries, regional sourcing, and tourism operations, especially because many visitors reach Siem Reap through hubs such as Bangkok, Singapore, or Kuala Lumpur.

The local currency is the Cambodian riel (KHR), although US dollars are also commonly used in parts of Cambodia’s tourism economy. The country dialing code is +855, so international callers reaching a hotel, guide, or business contact in Siem Reap will use Cambodia’s national prefix before the local number.
