When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Mountain Time and Novosibirsk don't overlap on the same weekday. Novosibirsk is 13 hours ahead of Mountain Time.
With some flexibility, there’s a workable window outside standard hours:
- 6 PM–8 PM in Mountain Time (7 AM–9 AM the next day in Novosibirsk) — suggest 7:00 PM Mountain Time (8:00 AM Novosibirsk).
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.
