Before you export
Does this connect to Google or Outlook?＋
No. The file is parsed on your device. This viewer does not request calendar account access.
Why does an all-day event end on the following day?＋
iCalendar uses an exclusive end date. An event on November 2 ends at the beginning of November 3.
Uses the iCalendar standard. Keep the original file and test the output in your receiving calendar app.
