Convert a specific time from GST to EST
Pick any time and date to convert it both ways. The conversion runs in your browser against the real zone rules, so a date inside a daylight saving period gets that period's offset rather than today's.
What is the time difference between GST and EST?
Eastern Time is 8 hours behind Gulf Standard Time. To go from GST to EST you subtract 8 hours. That gap is not fixed. Across 2026 the distance between these two zones takes 2 different values, from 8 hours to 9 hours, because Eastern moves its clocks and Gulf does not. This page recomputes it rather than assuming.

What are the best hours to schedule a call between GST and EST?
No hour of the standard 9:00 am to 5:00 pm working day falls inside working hours on both sides. Gulf and Eastern are 8 hours apart, which is too far for an overlap, so somebody has to take a call outside their own working day. The least painful options are below, ranked by how close both sides sit to the middle of the afternoon.
| GST | EST | Working hours | Note |
|---|---|---|---|
| 3:00 pm | 7:00 am | GST only | afternoon in Gulf, early morning in Eastern |
| 4:00 pm | 8:00 am | GST only | afternoon in Gulf, mid morning in Eastern |
| 5:00 pm | 9:00 am | EST only | evening in Gulf, mid morning in Eastern |
Does daylight saving change GST to EST?
Gulf Standard Time does not move its clocks at all, so its UTC+4 offset holds every day of the year.
Eastern Time is currently on EDT and changes next on Sunday, November 1, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC-4 to UTC-5.
Because the two sides do not move together, the answer to this conversion changes during the year. For part of the year the gap is 8 hours and for the rest it is 9 hours. The table above is built for today, not for an average day.
Is GST ahead of or behind EST?
GST is ahead of EST by 8 hours: when it is 12:00 pm in Gulf, it is 4:00 am in Eastern. One wrinkle worth knowing: EST and EDT are two names for the same zone, not two zones. Eastern Time reads EST in winter and EDT in summer. When somebody types "gst to est" they nearly always mean the zone rather than the literal winter offset, so this page resolves GST to Asia/Dubai and EST to America/New_York and applies whichever offset is genuinely in force on the day.
Gulf Standard Time covers Dubai, Abu Dhabi and Muscat. Eastern Time covers New York, Toronto, Atlanta and Miami. The identifiers behind them are Asia/Dubai and America/New_York, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
