Offset

MDT: UTC-6
Mountain Time is currently observing daylight saving time; Bangladesh Standard Time is not.
When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Bangladesh Standard Time and Mountain Time don't overlap on the same weekday. Mountain Time is 12 hours behind Bangladesh Standard Time.
With some flexibility, there’s a workable window outside standard hours:
- 7 PM–8 PM in Bangladesh Standard Time (7 AM–8 AM in Mountain Time) — suggest 7:00 PM Bangladesh Standard Time (7:00 AM Mountain Time).
This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.
This window may shift by an hour during daylight saving time.
Public holidays in 2026
National public holidays can affect availability — a counterpart is likely off work on their own holidays, so it's worth planning meetings and deadlines around them.
