Calendar Import Notes

Practical notes for diagnosing ICS calendar imports: snapshots, time zones, all-day boundaries, repeating events, and text encoding. Start with the symptom that matches your file.

1. Import or subscribe? Choose before troubleshooting

   events arrived once, but later changes never appeared.

2. Wrong hour? Separate the instant from its display

   everything is shifted by an hour, or an event moves when you travel.

3. All-day events: the end date is a boundary

   a two-day event displays as one day, or a holiday appears as a midnight appointment.

4. Repeating events, exceptions, and duplicate identities

   a moved occurrence appears twice, a skipped date returns, or re-importing fails to update an event.

5. Valid-looking text: escaping, folding, and UTF-8

   descriptions disappear, accented text breaks, or a file imports only partly.
