IST vs NZST — cities and working rhythm
Indian business hours run 10 AM – 7 PM IST typically; IT / BPO shifts commonly extend to cover US and UK working hours, so 3:30 PM – 12:30 AM IST (US overlap) and 12:30 PM – 9 PM IST (UK overlap) are the two second shifts you see most often. Weekend is Saturday-Sunday for most private-sector employers.
New Zealand winter offset (April to September), UTC+12 — one of the earliest zones to open the world business day. NZ summer flips to NZDT (UTC+13). 3-4 h ahead of Sydney seasonally.
Time gap: NZST is 6.5 hours ahead of IST (standard-time offsets — daylight-saving flips shift this by an hour twice a year in most northern-hemisphere zones).
