Scheduling Across Time Zones

If you've ever scheduled a meeting for "3 PM" and realized half your team missed it because they assumed 3 PM their time, you know time zones are a silent productivity killer.

💡 Expert Tip from David Chen, CFA

"For recurring global meetings, rotate the time monthly. 9 AM Pacific works for US teams but ruins Tokyo's evening. Next month, do 5 PM Pacific so Tokyo gets 10 AM. Share the pain fairly."

The "Impossible Meeting" Problem

You have teammates in San Francisco, New York, London, and Singapore. There's no good time for everyone:

  • 9 AM SF / 12 PM NY / 5 PM London / 1 AM Singapore ← Singapore dies
  • 5 PM SF / 8 PM NY / 1 AM London / 9 AM Singapore ← London & NY die
  • 6 AM SF / 9 AM NY / 2 PM London / 10 PM Singapore ← SF dies

⚠️ Common Mistake: Forgetting Daylight Saving Time

Your standing meeting is "9 AM Eastern" year-round. In March, the US springs forward but Europe doesn't (yet). Your European teammate shows up an hour late for 3 weeks. Always use UTC offsets or scheduling tools that handle DST automatically.

Best Practices for Global Teams

1. Always Specify Time Zones: Write "3 PM EST" or "15:00 UTC", never just "3 PM".

2. Use Scheduling Tools: Calendly, Google Calendar auto-convert to local time. Fewer mistakes.

3. Rotate Meeting Times: Don't always pick what's convenient for HQ. Rotate monthly.

4. Record Everything: If someone is joining at 2 AM, let them watch the recording instead.

Why UTC Doesn't Change

UTC (Coordinated Universal Time) is the global standard. It never changes for DST. That's why programmers use it for timestamps. Your local time zone shifts (EST → EDT), but UTC stays constant.

❓ Frequently Asked Questions

What's the best time for a global team meeting?

For US-Europe-Asia teams, 8 AM Pacific / 4 PM London / 12 AM Tokyo is the "least bad" option. Rotate meeting times monthly to share the burden.

Why doesn't UTC change for Daylight Saving Time?

UTC is the global standard and never changes. Local time zones shift for DST (EST → EDT), but UTC stays constant.

How do I avoid scheduling mistakes?

Always specify the time zone. Use "3 PM EST" not just "3 PM". Better yet, use Calendly or Google Calendar for auto-conversion.

What's the furthest time zone difference?

The maximum is 26 hours due to date line quirks. Samoa and Kiribati are 25 hours apart.
