Question

Any class or library in VBScript or asp classic that I can use to parse RRULE (iCalendar - RFC 5545) and generate a list of Upcoming Events?

Answer 1

you can try with rrule.js , is a javascript library , If you send RRULE string like

FREQ=DAILY;DTSTART=20150409T030000Z;UNTIL=20150511T025900Z;WKST=MO;BYDAY=MO,WE,FR
