Why people convert PET to Mumbai time

- Handling a +10h 30m gap: PET and Mumbai have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Mumbai is 7:30 PM in PET.
- Watching a live event or market open: PET viewers need 7:30 PM in Mumbai to catch a 9:00 AM start there, and 1:30 PM if the event is anchored to PET.
- Always state the zone abbreviation, not just the hour. "3:00 PM PET" is unambiguous; "3 PM" across a +10h 30m gap is not.
- With a +10h 30m gap there is no shared 9-to-5 window, so alternate the early start: one week PET takes the early slot, the next week Mumbai does.
