About UST
A fixed, year-round offset.
Uzbekistan Standard Time (UST) keeps things simple—no daylight saving clock changes, just a steady UTC+05:00 year-round across Central Asia’s Silk Road heartland. Whether you’re coordinating with partners in Samarkand or Tashkent, scheduling is refreshingly consistent in this historically rich region.
IANA zones · the technical identifiers
The 2 zones that resolve to UST.
For software, always store the IANA identifier — never the abbreviation alone. The database keeps these zones distinct because their rules can, and historically did, diverge.
Cities currently on UST

These named zones share UST's offset today. When daylight saving rules differ, they drift apart for part of the year.
Frequently asked questions
Common questions about UST, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Why doesn’t Uzbekistan Standard Time observe daylight saving time?
- Uzbekistan permanently stopped using daylight saving time in 1991 and chose to stay on a fixed UTC+05:00 year-round, eliminating the biannual clock confusion.
- How many time zones does Uzbekistan actually have?
- Uzbekistan uses a single time zone—All clocks in the country run on UTC+05:00 without variation across regions or seasons.
- Is there any chance UST will ever bring back DST?
- As of now, there are no known plans to reintroduce daylight saving; the country has maintained a stable offset since abandoning DST in 1991.
- What’s the best way to schedule meetings with Uzbekistan contacts?
- Their working hours (usually 09:00–18:00 local) map neatly to early afternoon slots in Europe and morning in parts of Asia—no seasonal surprises thanks to no DST.
- Does Samarkand and Tashkent ever differ?
- Both cities share the same time zone—Asia/Samarkand and Asia/Tashkent—clocks are synchronized down to the second, so you can treat them as one scheduling zone.
- What if my calendar ignores UST?
- Set a manual +05:00 offset or use 'GMT+05:00 (Tashkent)' if 'Uzbekistan Standard Time' is unavailable.
- Any famous local time traditions?
- Market vendors, ferrous-hour tea houses, and astronomy events all stick to the reliable UTC+05:00—for cultural immersion, sync your chats just a head earlier for evening bazaars.
