10.5: Two-way synch Google Calendars and iCal Apps
As noted in this post on the Google Code Blog, the Google Calendar now features support for the CalDV protocol:
The Calendar team was the first to launch its Google Data API back in 2006, and in that proud tradition, we're excited to offer an additional way for developers to read from, and write to Google Calendar: the CalDAV protocol. (CalDAV -- an extension of WebDAV -- is an evolving, open standard for calendar synchronization.)
What this means is that you can now do two-way synchronization between Google Calendars and iCal version 3.x (standard in Leopard). Google has some additional pages to help with the process: As noted by Google, this is a developer-focused release, and they strongly suggest that you restrict synchronization to test accounts only at this point.

[robg adds: I haven't tested this one; the hint is credited to pamon, as he's the one who emailed me the info on Google's CalDAV support. I wrote up the hint based on the links in pamon's email, so the above words (and any errors) are mine, not his.]

I was very excited about this when I read it over the weekend. But indeed this release of CalDAV is not ready for prime time. The "this may not work for all calendars" in one of the notes, for me it did not work with 3 out of 4 calendars. and then the one it did work for after a very smooth initial sync, things drifted apart very quickly.

This of course is all just a matter of time, eventually Google and Apple will both get it right. In the mean time folks should also look at SpanningSync (price drop ot $20 a year) and Calgoo (price drop to FREE). Both seem do do in different ways the syncing now.

Just be very careful with Googles CalDAV and make LOTS of backups.

This was pointed out on daringfireball.net a few days ago as a way to have a calendar not be included in MobileMe's iPhone sync, as it is not listed with the other local calendars and is treated sort of like a subscription calendar.

I was not able to get it to work reliably as I got this error for each event: "HTTP 1.1/409 Conflict"

I have this working with 4 different calendars on google, 2 Leopard machines and one Tiger. Its working peachy. I can even move events between calendars, either the normal way on the google calendar page, or by dragging and dropping an event from one calendar to the other in my icals.

My calendar syncing with my Palm pilot doesn't work too well with this, seems to sync from the mac and get events, doesn't write back to them however.

(That could be something wrong on the Palm end though, wasn't really paying much attention to my calendars on that before I did this, but when I enter a calendar event on my Palm, it sync's up on the mac and then to Google, but then its gone off my Palm. heh)

I've been syncing my three Google Calendars with iCal using CalDAV for around two weeks and I haven't had any major issues - though I haven't been making any major changes. My only two annoyances is that the alarms don't sync up and I still can't create events in the iphone without it creating a new calendar.

I have had the same experience. I read somewhere, but don't remember where, that Sync Services treats CalDAV calendars as though they are read-only, just like a subscription calendar, which is why if you try to add an event to one of these calendars on the iPhone it creates a new calendar.

Of course this also explains why if you use MobileMe all of the CalDAV calendars pretend not to exist at all on the iPhone.

As far as iCal, Google, and web integration goes I find this all to be working very well. I do find it very unfortunate that apparently Apple seems to think that any calendaring beyond one or two local only calendars is not necessary. 'Exchange for the rest of us' - Not exactly. Apparently the marketing genius that thought that up has not only not used Exchange, but even heard about what it is like to use it. Not that I like Exchange, but you can publish, subscribe, and share calendars with it.

This was working fine Monday (8/11) afternoon; but it appears to be broken now. There are widespread complaints on Google's discussion groups, so hopefully they'll remedy it quickly.

While it worked it was really slick!

Still broken here on 8/13. I would have loved this description one week ago when I did the setup by my self :-)
But until it broke, it worked perfect.
