Pretty good post, pretty good idea.
I've changed my password in November, I'm good.
I tend to change at random times, not necessarily at New Year's.

And yes, I recommend long password with random characters.
My password manager, Bitwarden, contains a great password generator, making a great combination. I recommend people consider using such a tool, it's much better than using same password or one with same "base" or "rule".

Happy New Year!
