CST to MST converter
MST is 1 hour behind CST right now. Central Time is the clock in Chicago; Mountain Time is the clock in Denver.
Why the gap stays the same
Central and Mountain time are one band apart and switch on the same dates. The boundary runs through the Dakotas, Nebraska, Kansas and Texas, so towns a short drive apart can be an hour apart.
