Why people convert China to Delhi time
- Scheduling a call from China to Delhi: a 10:00 AM start in China lands at 7:30 AM in Delhi, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both China and Delhi are inside the 9-to-5 working day between 11:30 AM and 5:00 PM CST time (9:00 AM–2:30 PM IST). That is roughly 5 hours 30 minutes of usable overlap.
- Booking travel or deliveries: tracking Delhi local time against China keeps pickup windows and arrival estimates honest across the -2h 30m offset.

- Block 11:30 AM–5:00 PM CST as the recurring meeting window if you work primarily from China and need Delhi colleagues present.
