Coordinating meetings across different time zones is one of the biggest challenges for global teams, remote workers, and international businesses. Whether you're scheduling a conference call with participants in New York, London, and Tokyo, or planning a webinar for attendees across multiple continents, finding a meeting time that works for everyone can be surprisingly complex.
Our free meeting planner calculator eliminates this complexity by instantly converting time zones, accounting for daylight saving time changes, and highlighting optimal meeting times when all participants are in their normal business hours. This comprehensive guide will help you master international meeting scheduling and make the most of our world clock meeting planner tool.
What are time zones and why do they matter? Time zones are regions of the Earth that have the same standard time. The world is divided into 24 primary time zones, each roughly 15 degrees of longitude apart. However, political boundaries and daylight saving time practices create over 40 different time zone offsets in use today.
Major time zones for business:
Follow these simple steps to find the perfect meeting time for your international team:
1. Aim for Overlapping Business Hours
The ideal meeting time is when all participants are in their normal working hours (typically 9 AM - 6 PM local time). Our calculator highlights these "green zone" times. For example:
2. Consider Rotating Meeting Times
When perfect overlap isn't possible (like US West Coast - Australia meetings), rotate meeting times so the burden isn't always on one time zone. One week meet at 6 PM PST (noon next day in Sydney), next week at 6 AM PST (midnight in Sydney).
3. Account for Daylight Saving Time (DST)
DST changes can shift meeting times by an hour! Important dates:
4. Be Mindful of Cultural Considerations
5. Use Clear Communication
When sending meeting invitations:
Scenario 1: US-UK Business Meeting
Time difference: 5 hours (EST to GMT) or 8 hours (PST to GMT)
Optimal times: 9 AM - 12 PM EST (2-5 PM GMT) or 1-3 PM EST (6-8 PM GMT). Avoid early morning UK times (before 2 PM GMT = before 9 AM EST).
Scenario 2: US-Asia Conference Call
Time difference: 12-13 hours (EST to Tokyo/Singapore)
Challenge: When it's day in US, it's night in Asia and vice versa. Best compromise: 7-9 PM EST (8-10 AM next day JST) or 6-8 AM EST (7-9 PM JST previous day).
Scenario 3: Europe-Australia Meeting
Time difference: 8-10 hours (CET to AEDT)
Optimal times: 8-10 AM CET (6-8 PM AEDT) or 5-7 PM CET (3-5 AM next day AEDT). Morning Europe = evening Australia works best.
Scenario 4: Global All-Hands Meeting (US-Europe-Asia)
Reality check: No perfect time exists for all three regions. Options:

Everything you need to know about scheduling meetings across time zones
A meeting planner calculator is a free online tool that helps you schedule meetings across different time zones. It automatically converts time zones, accounts for daylight saving time (DST), and shows you the best meeting times for all participants worldwide. Perfect for international teams, conference calls, webinars, and global collaboration. Our calculator supports 400+ cities and all major time zones including EST, PST, GMT, CET, IST, JST, and AEDT.
To schedule a meeting across time zones: 1) Select all participant locations in the meeting planner. 2) Choose your preferred meeting date. 3) The calculator will show available time slots color-coded by business hours. 4) Select a time that works for everyone (green zones indicate optimal times). 5) Export to your calendar or share the meeting time with participants. Our tool automatically handles DST changes and time zone conversions, making international scheduling effortless.
The best time for international meetings is typically during overlapping business hours (9 AM - 6 PM) for all participants. Use our meeting planner to find 'green zone' times when all locations are in their working hours. For example, for US-UK-Australia meetings, early morning US time (7-9 AM EST) often works as it's afternoon in UK (12-2 PM GMT) and evening in Australia (11 PM - 1 AM AEDT). Consider rotating meeting times for fairness when perfect overlap isn't possible. Avoid lunch hours (12-1 PM), weekends, and public holidays.
Our time zone meeting scheduler works by: 1) Converting all selected locations to a unified time reference (UTC). 2) Displaying a visual grid showing business hours for each time zone. 3) Color-coding time slots: green (business hours for all), yellow (business hours for some), red (outside business hours). 4) Automatically adjusting for daylight saving time changes. 5) Providing instant time conversion for any selected meeting time. The tool uses the official IANA time zone database and is updated regularly for 99.9% accuracy. It's 100% free and requires no registration.
Yes! Use our meeting planner to find the optimal time, then: 1) Find the best meeting time using our calculator. 2) Note the time in your local time zone. 3) Schedule your Zoom meeting at that time in your Zoom account. 4) Zoom automatically adjusts the invitation for each participant's time zone. 5) Share the Zoom link and participants will see the correct time for their location. This also works perfectly with Microsoft Teams, Google Meet, Webex, and all calendar apps including Google Calendar and Outlook.
Yes, our meeting planner calculator automatically accounts for Daylight Saving Time (DST) in all time zones.

This ensures accuracy year-round for locations like USA (March & November changes), UK/Europe (March & October changes), Australia (October & April changes), and other regions that observe DST. You never need to manually adjust for time changes - our calculator handles it all automatically.

When scheduling meetings across extreme time differences (like US-Australia or Europe-Asia-Americas), perfect times may not exist. Solutions: 1) Rotate meeting times so the burden is shared fairly (one week early morning for one group, next week late evening). 2) Record meetings for time-shifted viewing by those who can't attend live. 3) Hold two separate sessions (e.g., Americas-Europe and Americas-Asia). 4) Use asynchronous communication for updates that don't require real-time discussion. 5) Make attendance optional for those in extremely inconvenient time zones. 6) Keep meetings short (30 minutes) when requiring off-hours attendance.
