Making It Work
On a standard India day there is little or no real-time overlap with your hours. You can run it as an async handoff — work happens while you're offline and is ready in your morning — or have your specialist shift to your business day.
India Standard Time (IST) is UTC+5:30 and has no daylight saving; the other zones above follow daylight saving automatically. Zedtreeo specialists can work a standard IST day or shift to your business hours — agreed in your engagement.
Timezone FAQs
Working across timezones with India.
Most remote teams do well with 2–4 hours of daily overlap — enough for a standup, real-time decisions and quick reviews; the rest runs async. On India's standard day (9 AM – 6 PM IST) there is little or no natural overlap with a US 9-to-5: that day ends at 8:30 AM Eastern (7:30 AM in winter). US clients who want real-time hours have their specialist shift to their day — up to the full business day.
On a standard India day there is no natural overlap with a 9-to-5 Pacific day: 9 AM – 6 PM IST is 8:30 PM – 5:30 AM PDT (7:30 PM – 4:30 AM in winter, on PST). For real-time hours, the specialist works an evening or night shift in India — for example, 9 AM – 1 PM PDT is 9:30 PM – 1:30 AM IST. Zedtreeo specialists can work up to your full business day; the schedule is agreed in your engagement.
Yes. Specialists can work your business hours — up to a full 8-hour overlap with US time zones — and the schedule is agreed up front in your engagement. Some clients prefer an async handoff instead: the India team works a standard IST day while you are offline, and you review the work in your morning.
The winning combination: Slack for quick messages (with async expected response times), Loom for video walkthroughs and context-sharing, Notion or Google Docs for documentation, and a project management tool (Asana, Monday, Linear) for task tracking. Daily standup via video during overlap hours.
For most businesses, it's actually an advantage. With IST, your India team completes work during your nighttime — giving you 'follow-the-sun' coverage. Tasks assigned at your EOD are ready by your next morning. Many clients call this their productivity secret weapon.
Every Zedtreeo engagement includes a dedicated account manager who bridges the timezone gap. They ensure smooth handoffs, schedule overlap meetings, and handle any urgent communication during off-hours. Think of them as your timezone translator.
Methodology
How the Timezone Overlap Calculator works
How the number is produced
- Convert your working window to IST (UTC+5:30) and intersect it with a 9 AM–6 PM IST day (or the shifted window you choose).
- Overlap hours = length of the intersection; the tool also shows the shift a dedicated hire would work to give you full-day overlap.
- Recommendations follow the overlap: async-first, partial overlap, or full-day coverage.
Assumptions built in
- Daylight-saving changes in your region shift overlap by an hour twice a year — India does not observe DST.
- Dedicated staff can work your hours; the default IST window is only the baseline.
Benchmarks & sources
- IANA time-zone database (current)Used for: UTC offsets used in the conversion.
Methodology and constants last reviewed against the Zedtreeo pricing engine and Rate Index. Estimates are for planning; your quote depends on role, scope and engagement.
