Convert GST to WAT

WAT is 3 hours behind GST. GST is UTC+4 and WAT is UTC+1.

Best time to schedule a meeting

Standard 9–5 working hours overlap for 5 hours: 12:00 PM–5:00 PM GST (9:00 AM–2:00 PM WAT). Schedule meetings inside that window.

About GST

Gulf Standard Time (GST) is UTC+4. It is used in Dubai, Abu Dhabi and Muscat.

Gulf Standard Time is UTC+4, covering the United Arab Emirates and Oman, and there is no daylight saving anywhere on the Arabian peninsula. The scheduling complication in the region is not the clock but the week: the UAE moved its weekend to Saturday–Sunday in 2022, while Saudi Arabia and several neighbours keep Friday–Saturday, so a Thursday afternoon meeting lands differently across a border that has no time difference at all.

About WAT

West Africa Time (WAT) is UTC+1. It is used in Nigeria, Cameroon, Angola and much of central and western Africa.

West Africa Time is UTC+1 all year, with no daylight saving anywhere that uses it. It covers Lagos, Kinshasa and Luanda — a very large population on a single fixed offset. It matches Central European Time in winter and falls an hour behind it in summer, which means a standing Europe–Nigeria meeting moves twice a year at the European end and never at the African one.

Does this gap change with the seasons?

Neither GST nor WAT shifts with the seasons, so this 3-hour difference holds all year. That is unusual enough to be worth relying on: most cross-continental gaps move twice a year.

This is the reason scheduling systems store an IANA zone such as Region/City rather than an offset or an abbreviation: the zone knows its own rules and the offset does not.
