I've really wanted to put something in a public GitHub repository and now I finally done it! It is a calendar project for a 13 month calendar. Hello even accounting periods. Goodbye medieval aesthetics.

I could have kept refining it, but I just had to stop myself and put it out. It was my first TypeScript experiment, and I loved that. It was also the first time using new ECMA 2017 level features, and maybe the first time in decades that I did not use jQuery, which I always loved, but now I am saying goodbye.
