Best Time to Call Internationally
The best international call time is not simply the hour that looks convenient in your own calendar. A good slot respects local working hours, commute patterns, daylight saving changes, and the purpose of the call.

Key takeaways
- - Use 10:00 AM to 4:00 PM local time as the safest core window.
- - Check the exact date when daylight saving time may apply.
- - Rotate inconvenient recurring meeting times across regions.
Start with overlapping working hours
For most business calls, begin with a 9:00 AM to 5:00 PM window in each participant's local time. If the group spans more than six hours of difference, narrow that to 10:00 AM to 4:00 PM for the people who have the least flexibility.
For recurring meetings, rotate the inconvenience when no fair overlap exists. A weekly call between California, Nigeria, and Japan should not always land late for the same person.
Check the actual date
Daylight saving time means the difference between two places can change during the year. A call that is 4:00 PM in London and 11:00 AM in New York in one month may shift after one region changes clocks before the other.
Always check the exact meeting date for international calls scheduled more than a few weeks ahead.
Use call purpose to choose the hour
Sales calls, interviews, and customer calls usually work best in the recipient's mid-morning or early afternoon. Internal team updates can tolerate earlier or later hours if everyone agrees.
Avoid scheduling important decisions at the very edge of someone's working day. People may join, but the quality of attention is usually lower.
