Timezone Overlap Finder

How to Find the Best Time for Global Meetings

Scheduling meetings across multiple timezones can be a logistical nightmare. The Timezone Overlap Finder simplifies this by visually aligning the workdays of up to 4 different cities. By defining standard working hours (e.g., 9 AM to 5 PM), the tool highlights the overlapping "green zones" where everyone is typically at work.

Tips for Managing Multiple Timezones

• Share the Burden: If a team spans from California to India, an overlap during standard hours might be impossible. Rotate meeting times so the same person isn't always taking calls late at night or early in the morning.
• Be Clear with UTC: When proposing a time via email or Slack, always include the timezone explicitly (e.g., "10:00 AM PST / 6:00 PM GMT") or use UTC to avoid ambiguity, especially around Daylight Saving Time changes.
• Asynchronous First: Does it need to be a meeting? If there are no good overlapping hours, consider recording a video update or relying on well-structured written communication.

Examples of Common Overlaps

New York (ET) and London (GMT): Generally easy. The overlap is typically between 9:00 AM ET (2:00 PM GMT) and 12:00 PM ET (5:00 PM GMT).

San Francisco (PT), New York (ET), and London (GMT): The window narrows. A common sweet spot is 9:00 AM PT / 12:00 PM ET / 5:00 PM GMT.

San Francisco (PT) and Tokyo (JST): Very tricky during standard hours. Often requires someone to compromise, such as 4:00 PM PT / 9:00 AM JST (the next day).
