====== Calendar & Contacts Synchronization ======

===== Hints for Google Calendar =====

  * To create an event e.g. for the last Friday of each month:
    * Look for a month with 5 Fridays
    * Select the last Friday for the initial Event
    * Click on "Repeat ..."
    * Click on monthly, one month, repeat on day-of-week
    * Summary then shows "Repeat every month on last Friday"

  * Goggle-Kalender auf iPhone mit Google-Account synchronisieren:\\

===== Owncloud/Nextcloud Server =====

Used to provide CalDAV/CardDAV services.


==== Square contact photos in Nextcloud Calendar App ====

An easy workaround to change round photos to square ones would be to use the new theming_customcss
[[https://apps.nextcloud.com/apps/theming_customcss]] app with the following oneliner:

<code>
.contact__icon, .contactdetails__logo, .contactdetails__header avatar { border-radius: 0 !important; }
</code>
