CEST to MST Time Converter
Mountain Standard Time (MST) is currently 9 hours behind Central European Summer Time (CEST). CEST is UTC+2 and MST is UTC-7. The table below converts every hour of the day between the two, and the call planner shows where working hours line up.
Best Time for a Call
There is no overlap between 9:00 AM and 5:00 PM office hours in these two zones. Stretching to early mornings and evenings, the workable window runs from 4:00 PM to 9:00 PM in CEST, which is 7:00 AM to 12:00 PM in MST. One side ends up outside normal hours, so alternating who takes the awkward slot is a fair way to handle recurring calls.

MST is UTC-7. Most of the Mountain region switches to MDT (UTC-6) in summer, but Arizona stays on MST year round.
