Why people convert IST to Dubai time
- Scheduling a call from IST to Dubai: a 10:00 AM start in IST lands at 8:30 AM in Dubai, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both IST and Dubai are inside the 9-to-5 working day between 10:30 AM and 5:00 PM IST time (9:00 AM–3:30 PM GST). That is roughly 6 hours 30 minutes of usable overlap.
- Watching a live event or market open: IST viewers need 7:30 AM in Dubai to catch a 9:00 AM start there, and 1:30 AM if the event is anchored to IST.
- Always state the zone abbreviation, not just the hour. "3:00 PM IST" is unambiguous; "3 PM" across a -1h 30m gap is not.
- Block 10:30 AM–5:00 PM IST as the recurring meeting window if you work primarily from IST and need Dubai colleagues present.
