Hi 
Hopefully the developer of the contacts app is reading this 
The app works very good. The contacts app also creates a birthday calendar, that’s top!
What is created is something like “John Doe (*1980)”. It shows the year of the birthday, which is nice. But it would be also nice, if there would be shown how old the person is: “John Doe (37)”. If the string in brackets would be configurable, that would be awesome
Many greetings, Frank
Evolution is doing this
Thank you for your comment. “Evolution” seems to be an app for desktop systems.
What I need is a CalDAV and CardDAV system, which can host my contacts and automatically add birthday reminders to the cloud calendar, which is hosted on a Synology NAS, for example.
So the nextcloud Contacts App which is installable on a Synology NAS fulfills my needs quite good. Some more configuration options as mentioned would be great.
I don’t know if there are similar systems like the nextcloud Contacts App are available.
Many greetings, Frank
Well, I did a little hack and now there is also displayed the age.
In the file ~/apps/dav/lib/CalDAV/BirthdayService.php there is the string generated for the birthday calendar.
I replaced:
$summary = $title . ’ (’ . $summarySymbol . $date->format(‘Y’) . ‘)’;
by the following lines:
$actyear = date(‘Y’, time());
$age = (int)$actyear - (int)substr((string)$birthday, 0, 4);
$summary = $title . ’ (’ . $summarySymbol . $date->format(‘Y’) . ‘) [’ . $age . ‘]’;
Now you get for example the title “John Doe (*1980) [37]”
Many greetings, Frank
