I would check my calendar, but...

I'm one of those old-fashioned people who still use a small paper calendar. Originally a major reason was that I was very scared of my phone as a single point of failure: what if I had my calendar on my phone and then I lost my phone, then I would also lose all my appointments. Better I kept them separate and would (hopefully) only lose one or the other.
By now it's technically the opposite, I could have my calendar on my phone synced to elsewhere, while if I lose my paper calendar the info is just gone. But I got used to using it, and tbh I still like having it separate from my phone, so I can e.g. go through it more easily while on a call to make an appointment.

I used to buy a new pocket calendar in mid-December, and then I got one for Christmas once and since then I always bought them between Christmas and New Years. I enjoyed picking out a new pretty one every year. But I got sick after last Christmas and didn't get around to looking for one until this week - and, shockingly, it seems like there's almost no small pocket calendars left? It's only the second week of January!, but two stores didn't have any left, and another one only had one and that one I didn't like.
Annoying. I'm currently debating if I should check out more stores, if I should try to find one online, or if I should take this as a sign to finally switch to using my phone's calendar function.
