The 4h 30m offset between New Delhi and Sydney is not just a number — it reshapes the entire rhythm of collaboration. Sydney clocks out while New Delhi is still at lunch. Teams that don't plan this deliberately spend their overlap on firefighting instead of actual work.
The 3h 30m overlap window runs at the edge of both teams' days. For New Delhi's side it's a late-morning meeting; for Sydney it's early afternoon. Neither is painful, which is exactly why it works. Anchor your recurring sync here and treat the rest of the day as async territory.
Recurring calendar invites for New Delhi–Sydney meetings need a DST audit every year. If one city's clocks change before the other's, there's a window — sometimes three weeks, sometimes five — where the same calendar slot lands an hour earlier or later than intended. Always schedule with explicit timezone labels, not just clock times.
Add the rest of your team above and the planner scales to everyone at once. A three-city team spanning New Delhi, Sydney, and a third timezone often has less overlap than any two-city pair in isolation — surfacing that constraint early prevents scheduling that works on paper but burns people out in practice.
New Delhi is UTC+5:30 and Sydney is UTC+10, a difference of 4h 30m. This gap may shift by 1 hour during DST transitions.
The best meeting time is during the 3h 30m of shared business hours — typically 9:00 AM to 12:30 PM GMT+5:30.
Yes, partially. Sydney observes daylight saving time; New Delhi does not. Sydney's clocks change around October 4 and April 5, shifting the gap between the two cities by 1 hour for part of the year.
New Delhi and Sydney share 3h 30m of business-hours overlap (assuming 9 AM–5 PM local time for both).
