Making It Work
Limited real-time overlap means async workflows are essential. Structure work around clear daily deliverables, documented processes, and recorded video updates.
Recommended: Loom for context, Notion for specs, weekly video call during overlap window.
India Standard Time (IST) is UTC+5:30. Zedtreeo teams work 9 AM – 6 PM IST with flexible hours available.
Timezone FAQs
Working across timezones with India.
Most successful remote teams operate with 2-4 hours of daily overlap. This is enough for a morning standup, real-time decisions, and synchronous collaboration. The rest of the workday runs async. US East Coast clients typically have 4+ hours of overlap with IST.
PST has about 1.5-2 hours of natural overlap with IST standard work hours (your 7:30-9:30 AM). Many PST clients ask their India team to shift slightly (starting 10 AM IST) to get 3+ hours of overlap. Zedtreeo teams offer flexible scheduling.
Yes — flexible hours are available for an additional premium. However, most clients find that standard IST hours (9 AM – 6 PM IST) with async workflows actually increases productivity: your team works while you sleep, and you wake up to completed tasks.
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.
