UTC and GST on the World Map
The map below highlights the UTC (Coordinated Universal Time) and GST (Gulf Standard Time) timezone regions across the globe.
UTC – Coordinated Universal Time
UTC+00:00Coordinated Universal Time (UTC) is the world's primary time standard, used as the basis for civil time worldwide.
- •UTC is the basis for all civil time zones worldwide.
- •The abbreviation 'UTC' is a compromise between English (CUT) and French (TUC).
- •UTC is based on atomic clocks and is accurate to within a nanosecond per day.
- •Servers and databases worldwide store timestamps in UTC to avoid timezone confusion.
- •Leap seconds are occasionally added to UTC to keep it aligned with Earth's rotation.
GST – Gulf Standard Time
UTC+04:00Gulf Standard Time (GST) is used in the UAE, Oman, and other Gulf states, 4 hours ahead of UTC.
- •Dubai uses GST year-round with no daylight saving time.
- •GST is 9 hours ahead of EST and 4 hours ahead of GMT.

Time Conversion Guide: UTC to GST
UTC runs on Coordinated Universal Time (UTC) at UTC+00:00. GST runs on Gulf Standard Time (GST) at UTC+04:00. That puts UTC 4 hours ahead of GST — a difference of +4h at the current offsets.
In practice, when it is 9:00 AM in UTC it is 1:00 PM in GST. Midnight in UTC is 4:00 AM in GST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert UTC to GST time
- Scheduling a call from UTC to GST: a 10:00 AM start in UTC lands at 2:00 PM in GST, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both UTC and GST are inside the 9-to-5 working day between 9:00 AM and 1:00 PM UTC time (1:00 PM–5:00 PM GST). That is roughly 4 hours of usable overlap.
- Booking travel or deliveries: tracking GST local time against UTC keeps pickup windows and arrival estimates honest across the +4h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM UTC" is unambiguous; "3 PM" across a +4h gap is not.
- Block 9:00 AM–1:00 PM UTC as the recurring meeting window if you work primarily from UTC and need GST colleagues present.
About UTC (Coordinated Universal Time)
Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time. It is effectively the successor to GMT and is based on International Atomic Time with leap seconds added to keep it synchronized with Earth's rotation. UTC is used in aviation, computing, navigation, weather forecasting, and the International Space Station. Most programming languages and databases store timestamps in UTC.
About GST (Gulf Standard Time)
Gulf Standard Time (GST) is the time zone used in the United Arab Emirates, Oman, and other Gulf states. GST does not observe daylight saving time. Dubai and Abu Dhabi, major international business and tourism hubs, operate on GST.
Best time to call between UTC and GST
Both UTC and GST sit inside the 9 AM – 5 PM working day between 9:00 AM–1:00 PM UTC, which is 1:00 PM–5:00 PM GST. That gives roughly 4 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
UTC and GST overlap for about 4 hours during the working day — enough for meetings if you avoid the edges of the window.
UTC is 4 hours ahead of GST (UTC UTC+00:00 → GST UTC+04:00). The shared working window is 9:00 AM–1:00 PM UTC. Remember to re-check around daylight-saving transitions.
