Indochina Time (Bangkok)

Indochina Time (ICT) is UTC+7 year-round and covers Thailand, Vietnam, Laos, and Cambodia. Bangkok, Thailand's capital, is one of the world's most visited cities and the economic engine of mainland Southeast Asia. Thailand has never observed daylight saving time. The Stock Exchange of Thailand (SET) operates on ICT. Thailand's manufacturing sector, particularly automotive (it is the largest vehicle producer in Southeast Asia) and electronics, coordinates global supply chains from ICT. Bangkok's strategic position as an air hub — Suvarnabhumi Airport connects all of Asia — makes ICT a key scheduling reference. Thailand's tourism industry, one of the world's largest, serves visitors from every timezone. The one-hour difference from Singapore/Hong Kong (UTC+8) and the seven-hour difference from London create manageable business overlaps. Thailand's digital economy has grown rapidly, with Bangkok emerging as a regional startup hub. The country's famous street food culture, Buddhist temples, and tropical islands all operate on ICT. Vietnam, sharing the timezone, has its own booming tech sector in Ho Chi Minh City and Hanoi, making ICT increasingly important for Southeast Asian business.
