Understanding the -4h Gap: GST vs WET

GST runs on Gulf Standard Time (GST) at UTC+04:00. WET runs on Western European Time (WET) at UTC+00:00. That puts GST 4 hours behind WET — a difference of -4h at the current offsets.

In practice, when it is 9:00 AM in GST it is 5:00 AM in WET. Midnight in GST is 8:00 PM in WET. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert GST to WET time

  • Scheduling a call from GST to WET: a 10:00 AM start in GST lands at 6:00 AM in WET, so you can confirm the slot without doing the arithmetic yourself.
  • Finding shared working hours: both GST and WET are inside the 9-to-5 working day between 1:00 PM and 5:00 PM GST time (9:00 AM–1:00 PM WET). That is roughly 4 hours of usable overlap.
  • Coordinating a GST-based team with WET contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
  • Always state the zone abbreviation, not just the hour. "3:00 PM GST" is unambiguous; "3 PM" across a -4h gap is not.
  • Block 1:00 PM–5:00 PM GST as the recurring meeting window if you work primarily from GST and need WET colleagues present.

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.

About WET (Western European Time)

Western European Time (WET) is used in Portugal, the Canary Islands (Spain), Morocco, and several other locations. It is equivalent to GMT/UTC. During summer, Portugal and the Canary Islands switch to WEST (Western European Summer Time, UTC+01:00).

Best time to call between GST and WET

Both GST and WET sit inside the 9 AM – 5 PM working day between 1:00 PM–5:00 PM GST, which is 9:00 AM–1:00 PM WET. That gives roughly 4 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

GST and WET overlap for about 4 hours during the working day — enough for meetings if you avoid the edges of the window.

GST is 4 hours behind WET (GST UTC+04:00 → WET UTC+00:00). The shared working window is 1:00 PM–5:00 PM GST. Remember to re-check around daylight-saving transitions.
