Use Case

Finding the fairest time for a company-wide all-hands.

When your company spans 8 time zones, there is no perfect slot. The goal is the fairest compromise — and making sure no single region always takes the hit.

Why all-hands are the hardest meeting to schedule

An all-hands is uniquely difficult because:

• No flexibility: Everyone must attend. You can't skip the APAC team because they're "not essential."
• Large group: With 50+ people, the meeting can't easily shift 30 minutes to accommodate one region.
• Recurring: Monthly or quarterly all-hands compound the fairness problem. If the same region always gets the 10 PM slot, resentment builds.
• Executive presence: Leadership usually has the strongest opinion about timing — and they're often in the US headquarters.

Step 1: Map your regions

Before picking a time, know where your people actually are. Common all-hands configurations:

• US-only (4 zones): Eastern, Central, Mountain, Pacific — golden window is roughly 12 PM – 5 PM ET
• US + Europe: 9 AM – 12 PM ET overlaps with 2 PM – 5 PM GMT — comfortable for both
• US + Europe + APAC: Near-zero mutual overlap. This is where trade-offs begin.
• Global (6+ zones): No overlap exists. The question becomes: who takes the least-bad slot?

Best all-hands windows by company footprint

Use these standard-time starting points, then verify the exact date in the planner because DST transitions move the overlap by an hour.

Step 2: Use the planner to rank alternatives

1. Open World Clock Meeting Planner in International mode
2. Add one city per region (e.g., New York, London, Berlin, Dubai, Mumbai, Singapore, Tokyo, Sydney)
3. Set working hours: 9–5 for each region
4. Drag the meeting line to candidate times and note who's In hours, Early, Late, or Outside
5. Try 3–4 candidate times and compare the "Outside" count for each

The planner's In hours / Early / Late / Outside ratings make comparison instant. A slot with 1 Outside is better than a slot with 3 Outside — even if the first slot puts that 1 person at a slightly less convenient time.

Strategy 1: The rotating inconvenience model

Don't always make APAC take the 10 PM call. Rotate the pain across quarters:

• Q1: US-friendly time (10 AM ET / 3 PM GMT / 12 AM SGT next day)
• Q2: Europe-friendly time (9 AM GMT / 4 AM PT / 6 PM SGT)
• Q3: APAC-friendly time (10 AM SGT / 2 AM GMT / 9 PM ET previous day)
• Q4: Rotate back to US-friendly

Announce the rotation schedule so everyone knows it's fair. The planner's shareable links make it easy to show the team exactly why a particular time was chosen.

Strategy 2: The "two meetings" compromise

If the global all-hands is truly impossible (8+ zones, no overlap), consider splitting:

• Session 1: US + Europe — 10 AM ET / 3 PM GMT (both In hours)
• Session 2: APAC + US West — 10 AM SGT / 7 AM PT (both In hours)
• Recording: Record Session 1 and share with APAC. Record Session 2 and share with Europe.

This is more work to organize, but nobody gets a 3 AM call. Use the planner to verify both sessions land In hours for their respective audiences.

Strategy 3: The "async first" model

For truly global companies (US, Europe, India, Japan, Australia), the all-hands may work better as:

• Pre-recorded video: CEO records the update. Everyone watches at their 9 AM.
• Live Q&A: A 30-minute live session at the golden window for the most regions. Use the planner to find it.
• Async Q&A: Written questions in a shared doc, answered within 24 hours.

Making the trade-off visible

The hardest part of all-hands scheduling is getting leadership buy-in for a time that isn't perfect for everyone. The planner helps by making the trade-off concrete:

• Show the golden window (if it exists) — this is the best-case scenario
• Show the Outside count for each candidate time — "this slot puts 2 regions Outside, that slot puts 1"
• Show the In hours / Early / Late breakdown — Early is better than Outside
• Use Export → Slack summary to share the comparison with leadership

How to present to leadership

1. Open the planner with all your regions
2. Screenshot 2–3 candidate times with their ratings
3. Recommend the slot with the fewest Outside ratings
4. Acknowledge the regions that are Early/Late — and propose the rotation schedule
5. Attach the shareable link so leadership can verify themselves
