Choose which city keeps its local start time, convert the actual event date, and check the first session after every relevant clock change.
1. Use a city rather than a country label
Write Madrid, Mexico City or New York instead of relying on “Spain time”, “Mexico time” or “US time”. A country can contain several time zones. Confirm the participant’s actual city before copying an equivalence.
2. Convert the meeting date
The conversion for today may differ from next week. Use the event date and check the destination date too. A late-night origin start can fall on the previous day elsewhere.
3. Share an unambiguous invitation
Include the date, city and local clock for each participant. A calendar event stores a resolved UTC instant; review its local display after importing. Adding an event file does not send invitations by itself.
4. Review recurring sessions
The weekly checker shows four or eight proposed appointments at a fixed origin clock time. Its download contains independent events. For a recurrence created in your calendar, set its reference zone and inspect the occurrences after each transition, including the gap between Europe and New York.
Common questions
Does the downloaded ICS invite other people?
No. Review it after importing and add participants through your calendar application.
Where is the conversion calculated?
In your browser. Shared URLs expose selected cities, dates and times in the address.
