Scheduling Across MST and ART
For professionals scheduling meetings between MST and ART, finding overlapping business hours is essential. Standard business hours are typically 9:00 AM to 5:00 PM in each time zone. Given the 4 hours difference, the window of overlap may be limited. Use the highlighted working hours in the conversion table above to quickly identify suitable meeting times.
Daylight Saving Time Considerations
MST observes Daylight Saving Time, switching to MDT (UTC-6) during summer months. ART does not observe DST, staying at UTC-3 year-round. During DST transitions, the time difference between these zones may temporarily change by 1 hour. Always verify the current offset during spring and fall transition periods.
