Wellington is 7.25 hours ahead of Kathmandu
Best overlap: 8:45 AM to 10:45 AM in Kathmandu is 4:00 PM to 6:00 PM in Wellington.
Both teams are at their desks between 8:45 AM to 10:45 AM in Kathmandu and 4:00 PM to 6:00 PM in Wellington. You've got roughly 2 hours — enough for a focused daily check-in if you hold it at 8:45 AM in Kathmandu (4:00 PM in Wellington). One seasonal catch: Wellington springs forward and falls back, but Kathmandu doesn't, so the gap changes by an hour for several months of the year.
