Google Calendar .ics import Standards

Question

I have a .ics file that I generate from our database that works correctly in iCal, but is flaky in Google Calendar. Sometimes Google Calendar will import the file, but it does not pick up all the events.

Does anyone have any tips on the REQUIRED fields that Google needs? I am at a loss here as to why sometimes it won't import, or why it doesn't like some events. Some days we have 3 events, but Google only shows 1.

Searching elsewhere online does not really help, as it seems most other people are having this same issue.

Here is a sample of my formatting:

BEGIN:VCALENDAR
METHOD:PUBLISH
X-WR-TIMEZONE:America/Los_Angeles
CALSCALE:GREGORIAN
VERSION:2.0
PRODID:-//PUC Calendar// v2.0//EN

Answer 1

I was just having similar problems.

Deleting the UID or changing the number seems to work for me. (My vevents were numbered sequentially 1,2,...)
