Why people convert Delhi to PET time
- Scheduling a call from Delhi to PET: a 10:00 AM start in Delhi lands at 11:30 PM in PET the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -10h 30m gap: Delhi and PET 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 PET is 10:30 PM in Delhi.
- Watching a live event or market open: Delhi viewers need 10:30 PM in PET to catch a 9:00 AM start there, and 10:30 AM if the event is anchored to Delhi.
- Always state the zone abbreviation, not just the hour. "3:00 PM IST" 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 Delhi takes the early slot, the next week PET does.
