MST to CST (MT to CT): Mountain time to Central time

MST to CST time difference

Right now US Central Time is 1 hour ahead of US Mountain Time: when it is 9:00 AM in US Mountain Time (MDT), it is 10:00 AM in US Central Time (CDT). Both places change their clocks on the same nights, so the difference stays the same all year.

MT, MST and MDT; CT, CST and CDT

MT means Mountain Time, whatever the season. It is MST (Mountain Standard Time, UTC-7) from early November to mid-March and MDT (Mountain Daylight Time, UTC-6) the rest of the year. Today it is MDT. CT means Central Time, whatever the season. It is CST (Central Standard Time, UTC-6) from early November to mid-March and CDT (Central Daylight Time, UTC-5) the rest of the year. Today it is CDT. Most of Arizona stays on MST all year, so in summer Arizona has the same clock time as Pacific Time; this page follows Denver, which changes the clocks. Because all of these zones change their clocks on the same nights, the gap between MT and CT stays 1 hour all year. People often write "EST" all year when they mean Eastern Time; the times on this page are correct either way.

Scheduling tips

The gap is small, so normal working hours mostly overlap. When you share a time, write the zone with it, such as "9:00 AM MST", and remember that a time near midnight can fall on a different date on the other side.
