Wellington is 5 hours ahead of Jakarta
Best overlap: 8:00 AM to 1:00 PM in Jakarta is 1:00 PM to 6:00 PM in Wellington.
Aim for 8:00 AM to 1:00 PM Jakarta time — that's 1:00 PM to 6:00 PM over in Wellington. Around 5 hours of overlap is enough to work comfortably, as long as meetings don't drift to the end of one team's day. Because Wellington and Jakarta don't both observe daylight saving, plan to re-check the overlap around March and November.
