MST to CST Converter | Mountain to Central

The Mountain–Central corridor links Denver, Salt Lake City, and Boise with Dallas, Chicago, and Minneapolis. Energy companies, airlines, and agricultural businesses frequently coordinate across these neighbouring zones.

Central Standard Time is UTC−6 and Mountain Standard Time is UTC−7, producing a 1-hour gap. When it’s 9 AM in Denver, it’s 10 AM in Chicago. Both zones observe US daylight saving time on the same schedule, so the 1-hour offset is constant year-round.

As with other Mountain-zone pairs, Arizona is the exception. Arizona stays on MST year-round, so during summer the gap between Arizona and CDT widens to 2 hours instead of the usual 1.
