CST to MST Time — Convert Central Standard Time (US) to Mountain Standard Time (US)

MST is currently 1 hour behind CST.

On Clockjumper, CST refers to US Central Standard Time (UTC−6). The same three letters are also used for China Standard Time (UTC+8) and Cuba Standard Time (UTC−5) — check the city or UTC offset to be sure which is meant.

MST is Mountain Standard Time (UTC−7). Most of the US Mountain zone switches to MDT (UTC−6) in summer, but Arizona (except the Navajo Nation) stays on MST year-round.

The CST → MST offset stays constant across the year — neither zone shifts for daylight saving in a way that changes this gap.

MST is currently 1 hour behind CST.

What is the current CST to MST time difference?

Right now the gap is 1 hour — MST is 1 hour behind CST.
