We have a shared calendar with all seminar dates. Maintained by Christian and Julia in a collaborative effort, this calendar will always hold the latest info about seminar events, and some more stuff we think is relevant to the group.
You can see the calendar in a web page here.
Another way to access it is to subscribe to it with your favorite calendaring application.
To do that, select and copy this address:
Then go to e.g. Calendar.app and choose Calendar -> Subscribe (-> Abonnieren on German systems). Paste the entire address including the https://.
Accept and trust the security certificate, and confirm with your computer password.
Make sure to switch ‘Auto-Update’ on (set it to an hour or so).
The procedure is similar on smart phones and with other calendaring apps. Happy to help if you need setting it up!
