Target 8:00 AM to 12:00 PM in Auckland, which lands at 2:00 PM to 6:00 PM for the Denver side. A 4-hour overlap gives you a workable daily window; aim for earlier in it to avoid clipping the end of someone's day. Mind the calendar: when you pick a time, Denver will be on the previous day compared with Auckland. To edit hours, add more timezones, and share with your team, create a free collaborative board.
