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 MDT.

About these time zones
MDT: Mountain Daylight Time
Mountain Daylight Time is UTC−6.
Colorado, Utah, New Mexico, Wyoming, Montana and southern Idaho, plus Alberta, from March to November. Most of Arizona never uses MDT: it stays on MST all year.
CST: Central Standard Time
Central Standard Time is UTC−6. CST is also used for China Standard Time (UTC+8) and Cuba Standard Time (UTC−5). This page converts North American Central Time.
Texas, Illinois, Minnesota, Louisiana and most of the Midwest and South, plus Manitoba in Canada. Saskatchewan and most of Mexico stay on CST all year. CT is the short form for the whole zone.
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
Both zones change their clocks on the same dates (next on 1 November 2026), so the difference stays 1 hour all year.
