Rem2ics

Main article: Remind

A script that will convert Remind events to iCalendar format is here. It correctly handles details of the iCalendar format, including required properties, character quoting, line folding, correct EOL, and will recognize and handle recurring events.

Or the following simple script can be used to convert Remind events to iCalendar format. The output is suitable as a read-only format, but is not really designed to be edited (a REM statement that generates periodic reminders will be converted to separate iCal entries for every occurrence).

Among other uses, this script could be used to display your reminders via Google Calendar. Click "Manage calendars"->"Import Calendar" to import the ics file.
