Calgary is 8 hours behind Hamburg
Best overlap: 4:00 PM to 6:00 PM in Hamburg is 8:00 AM to 10:00 AM in Calgary.
Book within 4:00 PM to 6:00 PM Hamburg time (8:00 AM to 10:00 AM in Calgary) and both teams will be at work. The overlap barely stretches to 2 hours, so reserve it for what really needs a live conversation and handle the rest async.
