Geneva is 2 hours behind Moscow
Best overlap: 10:00 AM to 6:00 PM in Moscow is 8:00 AM to 4:00 PM in Geneva.
Both offices are open during 10:00 AM to 6:00 PM Moscow time, which is 8:00 AM to 4:00 PM in Geneva. Scheduling is forgiving here: with 8 hours of overlap, a missed slot just means picking another one the same day. Watch the DST gap — when Geneva changes its clocks and Moscow stays the same, this window slides by an hour.
