The Timezone Offsets That Matter
| Your timezone | Offset vs Delhi (IST) | 9:00 AM Delhi = your time | Live patch-in difficulty |
|---|---|---|---|
| US East (EST) | IST − 10.5h | 10:30 PM (prev day) | Late night, workable |
| US West (PST) | IST − 13.5h | 7:30 PM (prev day) | Easy evening slot |
| UK (GMT) | IST − 5.5h | 3:30 AM | Too early — book later IST |
| Gulf / UAE (GST) | IST − 1.5h | 7:30 AM | Easiest for live calls |
| Singapore (SGT) | IST + 2.5h | 11:30 AM | Easy |
| Australia East (AEST) | IST + 4.5h | 1:30 PM | Easy afternoon |
The question that decides your booking slot: do you want to join the consultation live (WhatsApp call patch-in) or review the summary after? Both work — they just need different timing.
US-Based NRIs
Delhi is 10.5-13.5 hours ahead of the continental US — the hardest pairing, but workable because Delhi hospital mornings land in your evening:
- Book 9-11 AM IST visits. The consultation typically happens mid-morning — your 7:30-9:30 PM (West Coast) or 10:30 PM-12:30 AM (East Coast) the previous evening.
- Afternoon IST slots (2-4 PM) land in US early morning (3:30-6:30 AM ET) — viable if you are an early riser.
- Government hospital token queues mean the actual consultation time can drift 1-3 hours — tell the companion you want a call when the token is close, not a fixed clock time.
Weekend Delhi visits map to your Friday/Saturday evening — often the least disruptive option.
UK & Gulf NRIs
UK: Delhi is 5.5 hours ahead (4.5 during UK summer time). A 9 AM Delhi consultation is 3:30 AM London — too early for most. Book 12-3 PM IST slots: your 6:30-9:30 AM, a natural pre-work window for a live call.
Gulf (UAE, Saudi, Qatar): Delhi is only 1.5-2.5 hours ahead — the friendliest pairing. Any daytime Delhi slot works for live patch-in; morning consultations land in your early morning, afternoon consultations in your late morning.
Singapore & Australia NRIs
The easiest pairing of all. Singapore is 2.5 hours ahead of Delhi; eastern Australia is 4.5-5.5 hours ahead. A Delhi morning visit lands mid-morning to early afternoon your time — normal working hours. You can follow the visit live on WhatsApp as it happens and patch into the consultation without disrupting your day.
When You Cannot Join Live
Even with the worst timezone math, nothing is lost — the whole visit runs async:
- Staged updates — WhatsApp photo/text at arrival, registration (token number), consultation start, pharmacy, and departure.
- Written summary (~2 hours) — doctor's name and department, assessment, medicines with dosage, and next steps — waiting in your inbox when you wake up.
- Record the questions — send the questions you want asked before the visit; the companion asks them in the consultation and notes the answers.
- Follow-up call — after you have read the summary, schedule a call with the companion or coordinator in your evening to discuss it.
