Is your feature request related to a problem? Please describe. I use a dedicated calendar to track the birthdays of people (who are not necessarily in my phone contacts). With recurring events this is pretty easy as one can repeat the event every year. What I'm missing though is a field where I can save their birth-year so that I can see how old they are at each of the later birthday events without manually calculating the age or increasing the age in the description field.

Describe the solution you'd like I see three nice scenarios:

• Add the ability for getting the past count of already happened events/tasks to use e.g. in the Description field of an event so that one can do things like: Description: Jon Doe becomes {count} years old today which then translates in each event/task to display as Description: Jon Doe becomes <number> years old today with <number> representing the count of past events/task.
• Introduce a dedicated field like Location or Description to do something similar to the above
• Make a dedicated type so that there are Task, Event and Birthday with proper fields in the latter to have an increasing age count in every recurring Birthday event.

Describe alternatives you've considered As I said, currently I manually calculate the age at the time I start to track a birthday and use the Description filed to store the age which needs a manual increase once the next birthday happens - really tiresome.

I also tried dedicated apps but I want to minimize the number of apps I install on my phone and the big downside of this approach is that now I have to check two apps which have date related stuff and it would be much nicer to have all things centralized in a single app.

Nice idea and alert notification would be great in order to not forget. Add a settings option alert at let user define hour of the day for all birthday to trigger notification

The app aCalendar has a nice feature. If you have or create an event wich is all day and repeats yearly, and have a valid four digit year in the beginning of the description field, it will also display the age/anniversary. So if I enter "Rudolf birthday" in Title and "1968” in Description the event will be displayed as " Rudolf birthday 57” if the event is all day yearly. This should be easy to code, needs no UI changes, and would help many aCalendar users switch to FOSS{ify).
