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.

About MST

Mountain Standard Time (MST) is UTC−7. It is used in Denver and Salt Lake City in winter, and Phoenix all year.

Mountain Standard Time is UTC−7. Denver and Salt Lake City use it in winter and switch to MDT in summer; Arizona does not switch at all and stays on MST year-round, which means Phoenix agrees with Denver in winter and with Los Angeles in summer. The Navajo Nation, inside Arizona, does observe daylight saving, so the state contains both. Any scheduling system that maps "Arizona" to "Mountain Time" without the no-DST flag will be an hour out for eight months.

Does this gap change with the seasons?

This gap is seasonal. The abbreviations themselves are fixed offsets, but the region on MST switches to MDT (UTC−6) from March to November. So the 9-hour figure on this page is correct for the part of the year when both places are actually on these abbreviations, and changes by an hour outside it.

SAST does not shift, so the whole change comes from one side. A recurring meeting fixed in SAST will appear to move by an hour for everyone on the other side, twice a year, without anyone changing anything.

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.

Frequently asked questions

What time is 9:00 AM SAST in MST?

9:00 AM SAST is 12:00 AM MST.

Is MST ahead of SAST?

MST is 9 hours behind SAST.

Which time zone does this use?

SAST is UTC+2 and MST is UTC−7. Both abbreviations denote a single fixed offset, so this conversion never shifts with daylight saving — what changes is which abbreviation a place is using at the time.
