Convert GST to SAST

SAST is 2 hours behind GST. GST is UTC+4 and SAST is UTC+2.

Best time to schedule a meeting

Standard 9–5 working hours overlap for 6 hours: 11:00 AM–5:00 PM GST (9:00 AM–3:00 PM SAST). 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 SAST

South Africa Standard Time (SAST) is UTC+2. It is used in South Africa, Lesotho and Eswatini.

South Africa Standard Time is UTC+2 with no daylight saving, unchanged since 1903 apart from two wartime years. The whole country keeps it, and so do Lesotho and Eswatini. Against the UK it is two hours ahead in winter and one in summer, which is the shift that catches London–Johannesburg standing calls every March and October.

Does this gap change with the seasons?

Neither GST nor SAST shifts with the seasons, so this 2-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.
