Worked Examples

Scheduling a Dubai-London business call at 10:00 AM Dubai time

Dubai is UTC+4. London is UTC+1 in summer (BST) or UTC+0 in winter (GMT). In summer: 10:00 AM Dubai = 10:00 - 3h = 7:00 AM London. In winter: 10:00 AM Dubai - 4h = 6:00 AM London. Always confirm which season applies — a call scheduled as 10 AM Dubai in December hits London at 6 AM, which may be too early.

Flight connection: departing Dubai at 23:30, arriving New York 12:15 next day

Dubai is UTC+4; New York in summer is UTC-4 (EDT), giving a difference of 8 hours. 23:30 Dubai = 23:30 - 8h = 15:30 EDT the same calendar day. The flight arrives at 12:15 New York time. Total flight duration = from 23:30 Dubai to 12:15 the next day NY = convert both to UTC: 23:30-4h = 19:30 UTC departure; 12:15+4h = 16:15 UTC arrival next day = 20h45m flight time.

Global team standup: finding a time that works across 4 zones

Team in Dubai (UTC+4), London (UTC+1 summer), New York (UTC-4 summer), Singapore (UTC+8). A 9:00 AM New York standup = 1:00 PM London = 6:00 PM Dubai = 9:00 PM Singapore. A 9:00 AM Dubai standup = 6:00 AM London (too early) = 1:00 AM New York (impossible) = 1:00 PM Singapore. Best shared window: 2-3 PM Dubai = 11 AM-12 PM London = 6-7 AM New York = 6-7 PM Singapore.

Frequently Asked Questions

~5 min read
What time zone is Dubai (UAE)?▾
Dubai and the entire UAE use Gulf Standard Time (GST), which is UTC+4. The UAE does not observe Daylight Saving Time — it is UTC+4 year-round, every day. This means the offset between Dubai and cities that do observe DST (London, New York, Paris) changes by one hour between winter and summer. Dubai is 4 hours ahead of UTC, 3 hours ahead of London in summer (BST), 4 hours ahead in winter (GMT).
Which GCC countries use the same time zone as Dubai?▾
UAE (Dubai, Abu Dhabi) and Oman share Gulf Standard Time (GST) at UTC+4. Saudi Arabia, Kuwait, Qatar, Bahrain, and Iraq are at UTC+3 — one hour behind Dubai. Iran is at UTC+3:30 (Iran Standard Time). None of the GCC countries observe Daylight Saving Time, which means their offset relative to Europe and North America shifts by 1 hour seasonally.
What is Daylight Saving Time and which countries use it?▾
Daylight Saving Time (DST) is the practice of advancing clocks by 1 hour in spring to extend evening daylight, then reverting in autumn. Major DST users: United States (second Sunday March to first Sunday November), European Union (last Sunday March to last Sunday October), UK (same as EU), Canada, Australia (southern states), and others. Countries that do NOT use DST: UAE, Saudi Arabia, Japan, China, India, Singapore, South Korea, most of Africa.
How do I convert Dubai time to New York time?▾
In summer (March-November approximately): New York observes EDT = UTC-4. Dubai = UTC+4. Difference = 8 hours. Dubai time - 8 = New York time. 10:00 AM Dubai = 2:00 AM New York. In winter (November-March approximately): New York observes EST = UTC-5. Difference = 9 hours. 10:00 AM Dubai = 1:00 AM New York. Always check the current offset with a live converter because exact DST transition dates change slightly each year.
What is UTC and how does it differ from GMT?▾
UTC (Coordinated Universal Time) is the international time standard, maintained by atomic clocks and broadcast globally. GMT (Greenwich Mean Time) is the solar mean time at the Royal Observatory in Greenwich, London. For all practical scheduling and timezone purposes, UTC and GMT are identical. The technical difference: UTC is defined by atomic standards and is slightly more precise than GMT, which follows the solar day. Modern systems use UTC; GMT is the common abbreviation for UTC+0 in British English.
How do I convert time zones without a calculator?▾
Step 1: Find the UTC offset for each zone (check a reference or look at the zone name — Asia/Dubai = UTC+4). Step 2: Convert your source time to UTC by subtracting the source offset. Step 3: Convert UTC to target time by adding the target offset. Example: 3:00 PM Dubai (UTC+4) to London (UTC+1 in summer): 15:00 - 4 = 11:00 UTC; 11:00 + 1 = 12:00 London (noon).
Why does the same flight take different hours depending on direction?▾
Flight duration (block time) is fixed by aircraft speed and distance. But the local clock time at arrival can vary greatly because of time zones and DST. A Dubai to London flight of 7.5 hours departing at 09:00 Dubai (UTC+4 = 05:00 UTC) arrives at 12:30 UTC = 13:30 London BST. The same flight in winter: 09:00 Dubai (05:00 UTC) arrives 12:30 UTC = 12:30 London GMT. The flight time is identical; only the local display changes.
What is the Nepal time zone (UTC+5:45)?▾
Nepal Standard Time (NPT) is UTC+5:45 — one of only four half-plus-hour offsets in the world (alongside India UTC+5:30, Sri Lanka UTC+5:30, and Iran UTC+3:30/4:30). This unusual offset was established to distinguish Nepal from its larger neighbors India (+5:30) and China (+8). In practice it means scheduling with Nepal involves minutes, not just hours: 12:00 Dubai (UTC+4) = 13:45 Kathmandu (UTC+5:45).
