Yes, I do, the nice ones, with beautiful pictures. In fact, I reuse them. Two of my 2019 calendars were reused from 2013. The full moons and some holidays don’t come out the same, but the days and dates do. There are, after all, only 14 different calendar configurations.
The 2020 ones won’t repeat, though, until 2048. I’m guessing I won’t be bothering much about them by then.
I used to keep the kitchen calendars because they were the master schedule, with everybody’s appointments, family birthdays and anniversaries, dates of major purchases, and all sorts of other stuff on them. I saved them as a record of events. That lasted until my son decided to cut up the old ones for some obscure project and my chronicle disappeared. Now I keep a personal desk calendar for that purpose.
One of my New Year’s Day rituals is to copy the recurring dates from the old master calendar to the new, all the nieces’ and nephews’ birthdays and everything. It’s a nice start to the year.
Packrattishness, now, that’s a different matter, if you ask me.
