Publishing International Event Times
An event time is only useful if the audience can understand it quickly. For international events, the best listing includes the host time zone, UTC offset, date, and converted examples for the largest audience regions.

Key takeaways
- - Publish one official host time and date.
- - Include converted examples for the main audience regions.
- - Avoid relative wording for international announcements.
Use one official host time
Choose one primary time zone for the event, usually the organizer's city or the production location. This prevents different teams from editing different versions of the same announcement.
Write it with the date, weekday, time, and time zone. For example: Thursday, June 18, 2026, 4:00 PM London time.
Add regional conversions
If your audience is global, include a short list of converted times for major regions. A webinar audience might need New York, London, Lagos, Dubai, Delhi, Singapore, and Sydney.
Do not overload the announcement with every possible country. Link to a time conversion or meeting planner for people outside the main regions.
Mention daylight saving when relevant
When an event is promoted weeks ahead, daylight saving can change the time difference before the event date. Confirm the conversion against the actual event date.
This is especially important for recurring classes, livestream schedules, and product launches that span several months.
Keep the language unambiguous
Avoid phrases like tomorrow, tonight, or end of day when the audience spans time zones. These phrases depend on the reader's location.
Use absolute dates and named time zones so the announcement remains clear when copied into emails, social posts, and calendars.
