MST to CST converter

When it's 9:00 am in Denver, it's 10:00 am in Chicago. Your 9-to-5 working days overlap for 7 hours, so there's room for a meeting most days.

Convert Mountain Standard Time (MST) to Central Standard Time (CST) for any date and time.

Central Time is 1 hour ahead of Mountain Time all year.

Right now Mountain Time is on MDT (UTC−6) and Central Time is on CDT (UTC−5). Both switch back to standard time on 1 November 2026.

US clocks go back on 1 November 2026. From then, CST is still 1 hour ahead of MST.

9:00 am to 5:00 pm MST is 10:00 am to 6:00 pm CST.

Most places on Central Time are on CDT (UTC−5) right now, not CST. People still say "CST" all year, so the times on this page follow the clocks and show CDT until 1 November 2026.

How the difference changes
