Options

Timed and all-day: Timed events use an instant derived from the entered zone and local time. An all-day event uses date values with an exclusive end date.
Repeated time choice: When a local time occurs twice, select the intended occurrence. The exported timed values use the supported UTC convention.

Supported inputs and limits

One nonrecurring event, dates 1970–2100, using explicit UTC export for timed events or exclusive end dates for all-day events. Named zones use browser IANA rules. Clock gaps are refused; repeated times use your earlier/later choice. No attendees, alarms, account connection or recurrence.

Where your input is processed

This tool processes your input in this browser. Your text and files are not uploaded to UseFreeTools. Check this tool's limits for anything it may save on your device.

Inspect the imported event before inviting anyone

The file is created locally and does not contact a calendar account. An importing application controls reminders, display timezone and invitations. Review the start and exclusive end after import, especially for all-day events and clock-change dates.

Questions about Calendar Event File Generator

Why is an all-day end date exclusive?

It identifies the first date after the event. A one-day event ends on the following date.

Does generating a file add it to a calendar?

No. Review the file and import it in your calendar application if you choose.

Can future timezone rules change?

Yes. The selected browser data resolves the event now; review future dates when policies change.
