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.
CDT: Central Daylight Time
Central Daylight Time is UTC−5. CDT is also used for Cuba Daylight Time (UTC−4). This page converts North American Central Time.
Texas, Illinois, Minnesota, Louisiana and most of the Midwest and South, plus Manitoba, from March to November. Saskatchewan and most of Mexico don't switch to CDT.
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.
