Daylight saving and how the gap changes

The CDT → MST offset stays constant across the year — neither zone shifts for daylight saving in a way that changes this gap.

Frequently asked questions

Is MST ahead of or behind CDT right now?

What is the current CDT to MST time difference?
Right now the gap is 1 hour — MST is 1 hour behind CDT.
Does the CDT → MST offset change during the year?
No. Neither Central Daylight Time (US) nor Mountain Standard Time (US) shifts for daylight saving in a way that changes this offset — the gap is the same all year.

Does MST observe daylight saving time?
MST is itself the standard-time form. Mountain Standard Time (US) is in force at UTC-7 through the winter months; outside that window the same zone is on MDT (UTC-6).
