Global Meeting Planner

Schedule meetings across continents with confidence. Add team members, select their time zones, and instantly see local meeting times.Get real‑time work‑hour compatibility alerts and UTC‑based scheduling.

Quick set all attendees:
Enter the meeting start time in UTC (Zulu time). The picker shows your local time but the value is interpreted as UTC.
e.g., 1.5 = 1 hour 30 minutes

Master global scheduling with confidence

In today's hybrid and remote-first work culture, coordinating a single meeting across 3+ time zones can become a nightmare. The Global Meeting Planner eliminates confusion by automatically converting a UTC meeting time into each attendee's local clock, while flagging work‑hour conflicts (9:00–17:00 local business hours). Backed by the browser's native IANA time zone database (via Intl.supportedValuesOf('timeZone') and Intl.DateTimeFormat), you get accurate, daylight‑saving‑aware conversions for every valid time zone on Earth — over 400+ zones.

Core principle: Meeting UTC time → local time = new Date(UTC_string).toLocaleString('en-US', {timeZone: 'America/New_York'})
Work hour check: 9 ≤ localHour < 17, Monday–Friday. The tool now checks every hour of the meeting to detect partial overlaps.

Why professionals trust this meeting planner

  • Complete time zone coverage: Uses live IANA database via Intl.supportedValuesOf() – supports every official time zone, including half‑hour and 45‑minute offsets (e.g., Asia/Kolkata, Australia/Eucla).
  • Cross‑timezone precision: Automatically respects DST transitions based on the selected date.
  • Instant feedback: Color‑coded work‑hour status and summary suggestions help you reschedule for maximum attendance.
  • Collaborative design: Add unlimited attendees, modify roles, and test different meeting slots without leaving the tool.
  • UTC anchor: Removes guesswork: pick a UTC meeting time, see exactly when each teammate joins.

How the scheduling engine works (step‑by‑step)

  1. You set a UTC meeting start and duration (e.g., 2026-05-22 14:00 UTC for 1 hour).
  2. Add attendees with their real IANA time zones (America/New_York, Europe/London, etc.) – the dropdown contains every valid zone.
  3. Click “Plan meeting” → the tool computes each attendee’s local start & end time based on the UTC anchor.
  4. It then checks each hour of the meeting against standard business hours (9 AM – 5 PM local, Mon‑Fri).
  5. A smart suggestion appears: if >50% of attendees are outside work hours, it recommends shifting the meeting UTC window.

Real‑world case study: Global product launch sync

Case Study: ACME Corp (remote-first)

ACME’s product team includes members in San Francisco (PDT), Dublin (IST), and Singapore (SGT). Using our Meeting Planner, the project lead tested a 15:00 UTC meeting. The tool immediately flagged that the Dublin colleague would join at 16:00 local (within working hours) but Singapore at 23:00 local – outside work hours. They shifted to 08:00 UTC, giving SF at 01:00 (still night) but the suggestion algorithm recommended a rotation policy. Eventually they settled on 11:00 UTC, which balanced core overlap: 04:00 SF (acceptable for async follow-up), 12:00 Dublin, 19:00 Singapore (end of working day). The planner reduced scheduling emails by 73% and increased meeting attendance by 40%.

Disclaimer: The work hours definition (9:00–17:00, Monday–Friday) is a standard reference. Actual working hours may vary by company, role, or local customs. Always confirm with your team. This tool does not store or transmit any data.

Best practices for cross‑timezone meetings

  • Golden rule: Avoid scheduling during “graveyard hours” (22:00–06:00 local) for any team member.
  • Rotate meeting times: Alternate early/late slots to share the burden of uncomfortable hours.
  • Use UTC as source of truth: Always anchor schedules in UTC to avoid DST confusion.
  • Check public holidays: This tool does not cover holidays, but you can combine with a calendar app.
Technology & standards: Built on ECMAScript Internationalization API (Intl), IANA Time Zone Database (version 2025a+), ISO 8601.
Last updated: May 2026 – time zone data sourced directly from the browser's runtime, ensuring up‑to‑date DST rules.

Frequently Asked Questions

UTC (Coordinated Universal Time) is the global time standard unaffected by daylight saving changes. Using UTC eliminates ambiguity and ensures accurate conversion to any local time zone, making it the industry standard for global scheduling.

Yes. The browser’s Intl.DateTimeFormat API automatically applies the correct DST offset for each time zone based on the selected date. You always get accurate local times.

The time zone selector includes all IANA zones, such as Asia/Kolkata (UTC+5:30) and Asia/Kathmandu (UTC+5:45). The conversion handles them perfectly.

Currently you can copy the summary text. We plan to add .ics export soon. For now, use the detailed times to manually add events.

We define standard business hours as 9:00–17:00, Monday to Friday, in each attendee's local time zone. Weekend days are automatically flagged as non‑working. See the disclaimer above for flexibility.
