I found the perfect yearly calendar (for me)

Our local MP (I'm in Sydney) distributed a piece of magnetic calendars to every household, which can be attached to the refrigerator. All the public holidays are already marked, and I mark my own special ones with a highlighter. It's really useful, as long as you don't mind seeing the MP's photo every day.

I hate to be that guy, but why not use pscal ?

It has all you want, plus moon phases!

It's admittedly harder to find these days, and someone should rewrite it in a decent language, but here it is:

I like a version of this[0] where the weekdays are aligned.

I have a simpler problem - I want a yearly calendar app (for Android) that just shows the yearly calendar (for any year), nothing else (no events, no reminders, no anything).

Any app I find seems to disappear from the Play Store after a couple years.

Bonus: show the weeks vertically.
