What time-zone overlap can I expect from India?

Canada spans six time zones (UTC-3.5 Newfoundland to UTC-8 Pacific). India is fixed at IST (UTC+5:30). The realistic daily overlap, working Indian working hours (10:00–19:00 IST):

• Atlantic / Newfoundland (UTC-4 / -3.5) — ~30 mins overlap with very early IST mornings
• Eastern (Toronto, Montreal, Ottawa — UTC-5) — 1–3 hours/day overlap (your 7–9am ET = our late evening)
• Central (Winnipeg — UTC-6) — ~1 hour/day overlap
• Mountain (Calgary, Edmonton — UTC-7) — ~30 mins overlap
• Pacific (Vancouver — UTC-8) — 0–1 hour/day overlap (mostly async)

In practice we run two overlap windows: 7–9am ET (5:30–7:30pm IST) for daily standups with East-Coast clients, plus a 9–10am ET / 7:30–8:30pm IST window for urgent calls. For West-Coast clients we shift to 8–10pm IST / 7:30–9:30am PT. Async-first via Slack + Loom + GitHub for the rest.
