Current Time in Hanoi

About time in Hanoi

Hanoi observes Indochina Time, abbreviated ICT, at a constant UTC+7 offset with no daylight saving changes. All of Vietnam uses this single zone, so the capital in the north and Ho Chi Minh City in the south always share the same clock. In the IANA database the zone is identified as Asia/Ho_Chi_Minh, even though it covers the entire country including Hanoi. Indochina Time is shared with neighbors such as Thailand, Cambodia, and Laos, making cross-border scheduling across mainland Southeast Asia simple and consistent.

Hanoi does not make seasonal clock changes under its current rules. Its offset is UTC+7 (no DST). The live clock above reads Hanoi's local time directly from the IANA time zone database in your browser, using the rules installed on your device.

Daylight in Hanoi through 2026

Hanoi sits at about 21.0°N, 105.8°E. The longest day of 2026 is June 19, with 13h 25m between sunrise and sunset. The shortest is December 17, with 10h 51m, a difference of 2 h 34 min. At this latitude the seasons change day length noticeably but not dramatically, so the working day has usable daylight all year.

The earliest sunrise of the year comes around June 1 (05:14) and the latest sunset around July 2 (18:42). These are not exactly on the solstice because the sun’s position runs slightly ahead of or behind clock time during the year.

Solar noon, when the sun is highest, falls at about 12:03 local time in late March, 11:58 in late June and 11:54 in late December. In standard time the sun is highest at about 11:57 on average, close to 12:00, so the clock and the sun are well aligned in Hanoi.
