What MDT and CT Actually Are
MDT — Mountain Daylight Time
Denver, Salt Lake City, Calgary, Edmonton. Standing at UTC-6:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to MST.
Because Arizona does not follow it, MDT is the half of the year when Phoenix and Denver read the same clock despite being in different zones.
CT — Central Time
Chicago, Houston, Dallas, Mexico City, Winnipeg. Standing at UTC-6:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to CST.
Central Time is the widest US zone by land area, stretching from the Gulf coast to the Canadian border, and it also covers Mexico City.
What This Means in Practice
Both sides change clocks, on different dates
Both regions observe daylight saving but do not switch on the same day, so for a week or two each spring and fall the gap between them is an hour different from the rest of the year. Those short windows are where recurring invitations quietly break.
Close enough to share a working day
At only 1 hour apart, the two working days overlap almost completely. Scheduling is barely constrained by the difference.
