When daylight saving changes the gap

2026

Central Time (US) is 1 hour ahead of Mountain Time (US) all year.

Mountain Time (US) moves its clocks forward on March 8 (2:00 AM becomes 3:00 AM) and back on November 1 (2:00 AM becomes 1:00 AM). Central Time (US) moves its clocks forward on March 8 (2:00 AM becomes 3:00 AM) and back on November 1 (2:00 AM becomes 1:00 AM).

Both switch at 2:00 AM local time, which is a different moment in each zone, so for about an hour on March 8 and November 1 the gap is briefly different.

What MST and CST mean here

MST means US Mountain Time as kept in Denver, Salt Lake City, Albuquerque and Calgary: MST (UTC−7) in winter and MDT (UTC−6) from March 8 to November 1, 2026. Arizona is the exception: most of the state stays on MST all year, so in summer Phoenix shows the same time as Los Angeles, not Denver.

Here CST means US Central Time: Chicago, Dallas, Houston, Minneapolis, New Orleans and Winnipeg. That's CST (UTC−6) in winter and CDT (UTC−5) from March 8 to November 1, 2026. CST is also the abbreviation for China Standard Time (UTC+8) and Cuba Standard Time; for China, search for Beijing or "China Standard Time" in the converter.
