I make these wall calendars every year with one big image in the background or twelve themed images in alternating squares.
I note the birthdays of friends and relatives (and cats) with their name on the date plus a bright gold star behind it. (To protect privacy I’ve changed them all to “Name” here, but you get the idea.)
This sitting tattooed cat is a stock image. I added the red-to-blue radial gradient, and sized and positioned the image so the cat’s face looks out through an empty space.
