I wanted to make my girlfriend a birthday gift. She likes the yearly grid journaling style where you color in each cell according to a legend. This listing on Etsy being a great example of the format.
Since the design is pretty simple, I figured I could make a generic template in LaTeX for both her use and anybody else who likes the journaling technique.
The problem is, I haven't meaningfully used LaTeX in years! However, in under an hour of chatting with Perplexity AI I managed to throw together almost exactly what I had in mind. For the curious, this is the thread.
