Asian Time Zones
Asia spans the widest time zone range of any continent, from Pakistan (UTC+5) to Japan (UTC+9). Most Asian countries do not observe daylight saving time, making their offsets consistent year-round.
No seasonal clock changes in most of Asia. China, Japan, South Korea, India, Singapore, and Thailand all stay on their standard time year-round — no spring forward or fall back.

Why Does Asia Have So Few DST Countries?
Most of Asia lies between the tropics and mid-latitudes where seasonal variation in daylight is relatively small. This makes DST less beneficial — the energy savings and agricultural arguments that drove adoption in Europe and North America are weaker or absent.
India is notable for using a single time zone (UTC+5:30) across a country that spans over 30 degrees of longitude — approximately the same east-west extent as Western Europe, which uses 4 zones. China similarly uses a single zone (UTC+8) for political unity, despite geographically spanning 5 theoretical zones.
Japan and South Korea both experimented with DST in the late 1940s (during US occupation) but abolished it due to public unpopularity. Neither country has reintroduced it since.
