Can Adobe Photoshop Elements 2020 app in the App store construct and print multi month wall calendars?
Any version of photoshop can be used to print wall calendars. I would probably use Illustrator or another tool, but since you can subscribe to these for a month by month basis - it should be easy for you to decide if it’s worth it or you use a different app.

There’s also a free trial of elements if you want to avoid the full CC apps and go with something you license at fixed cost.

Since so few Adobe apps are on the MAS, you might be happier getting it direct from them.
