Exporting One All-Day Event to an ICS File

Illustrative example. The dates and amounts below are provided for practice.

A one-time graduation on December 8, 2027 needs to be copied into another calendar without exporting the rest of the household's dates.

Make a small file

1. Save “Graduation ceremony” as Graduation, December 8, 2027, One time.
2. In the exporter, choose Selected dates and select only that title.
3. Leave alarms off for this initial test and download ICS.

Inspect the file or a test import. The event starts with an all-day date value of 20271208 and ends with 20271209. There should be one event and no annual recurrence rule.

Explain the next-day end

ICS uses an exclusive end date. December 9 as the end means the event occupies December 8 only. Changing the end to December 8 would not be the correct way to describe a full all-day event.

The span is one elapsed calendar day from its start to its exclusive end.

Verify the receiving calendar

Import into a separate test calendar if possible. Check the title, date, all-day placement, and absence of an annual repeat before keeping the imported copy.

This site exports dates rather than timed appointments. Add a ceremony time in the receiving application if needed, and avoid claiming the ICS file itself specified an hour.
