@sdetweil Okay, I’ll send the file directly. It’s large and pulling out all the personal info would be a chore.

Time zone issues would make sense with my work calendar. I’m in Central time, the company office is on the East Coast, and a meeting series on my calendar which is messed up is from a client on Mountain time. Still, some events are fine. Maybe it depends on who at HQ schedules it. Don’t know. The personal calendar is on local time, so I’m not sure why one or two events in it would behave differently than others. I’ve pulled the ics files and stripped each down to a handful of events with comments about whether or how they were affected.

First the personal calendar:

I’ve tried this with the default Calendar module and ones that depend on it, and I’ve tried Ext2 as well. I’ve referenced both Google calendars in question by their ics link. With the default calendar and related modules, most events are right, but some are missing, some show an hour early, and some an hour late. The Ext2 module came closer, but even it is missing at least one important recurring event. I’d love to get it working with the default module so I can use it with ext3 and run it on my pi0w without having to run the server on something else.
