Scheduling a call between HST and NZST
Standard business hours (9:00 AM to 5:00 PM) do not overlap in January: daytime in Hawaii Standard Time falls outside the working day in New Zealand Time, so one side needs an early morning or late evening.
In July standard business hours do not overlap at all.
