Current time in Phnom Penh, Cambodia

The current local time applies throughout the Phnom Penh municipality, from its central districts to its expanding outer districts. There is no clock change when travelling between Phnom Penh and another part of Cambodia because the entire country follows the same time zone.

To calculate Phnom Penh time from UTC, add seven hours. If the result passes midnight, advance the date as well. For example, an evening UTC time may already correspond to the following morning in Cambodia.

Phnom Penh traffic can alter an arrival time far more dramatically than the time zone does.

Planning calls and arrivals in the capital

A fixed UTC+7 offset makes local scheduling straightforward, but international comparisons need attention. Phnom Penh never changes its clocks seasonally. A caller in a country that observes daylight saving time may therefore find that the difference from Cambodia changes during the year.

Use ICT or UTC+7 for Phnom Penh’s time zone. Do not apply a daylight-saving adjustment to the Cambodian side. Include the date when arranging late-night or early-morning calls. Check an airline or transport booking in the local time printed on the ticket.

Allow travel time separately from the scheduled clock time. Phones and computers normally identify the capital through an Asia/Phnom_Penh setting or an equivalent automatic location choice. A fixed-offset UTC+7 setting displays the correct civil hour, although a named regional setting is generally clearer when calendars are shared across devices.

Districts, urban time, and sunrise

Phnom Penh is both Cambodia’s capital and a municipality. Rather than containing a collection of separate major cities, it is divided into urban districts and neighbourhoods that form one metropolitan area. Central places and peripheral communities all use the same official time.

Sunrise changes gradually over the calendar even though the clock offset remains constant. A sunrise table describes the calculated moment when the Sun reaches the horizon for a specified location. Buildings and the urban skyline can prevent an observer at street level from seeing it at exactly that moment.

For a riverside walk, market visit, flight, or early road departure, consult the date-specific sunrise and dawn information. Dawn begins before sunrise, and useful visibility depends on cloud, rain, haze, and the surrounding structures. Sunset should likewise be checked for the particular day rather than assumed from a previous trip.

Questions and answers
What is Phnom Penh’s UTC offset?
The capital uses UTC+7, known as Indochina Time.
Does the time change between Phnom Penh and Siem Reap?
No. Both places, like the rest of Cambodia, use the same national time.
Why might visible sunrise differ from the listed time?
The calculation uses an ideal horizon, while buildings, weather, and the observer’s position can affect when the Sun is actually seen.
