Why people convert Delhi to Tokyo time
- Scheduling a call from Delhi to Tokyo: a 10:00 AM start in Delhi lands at 1:30 PM in Tokyo, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Delhi and Tokyo are inside the 9-to-5 working day between 9:00 AM and 1:30 PM IST time (12:30 PM–5:00 PM JST). That is roughly 4 hours 30 minutes of usable overlap.
- Coordinating a Delhi-based team with Tokyo contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM IST" is unambiguous; "3 PM" across a +3h 30m gap is not.
- Block 9:00 AM–1:30 PM IST as the recurring meeting window if you work primarily from Delhi and need Tokyo colleagues present.
