Having a “remainder day” is weird, but it’s hard to avoid. It really sucks that 365 doesn’t divide nicely into much at all. 5 and 73 are the only non-trivial answers. five 73 day months? Can’t even call it a month at that point.
I guess 13x28 + 1 does indeed make most sense…
My problem with Lemmy is the lack of activity in niche communities. You’re right that there needs to be a critical mass and arguably Lemmy has it, but only for the most mainstream, generic type of content. It doesn’t have the mass to sustain any sort of niche, outside of maybe tech related topics because of the way the userbase is slanted.
I find myself going back there often because of that, but I hope that the userbase for generic content enough to sustain and grow, from where more active niche communities can spring up.
speaking of leap days, I also considered using a quad-year as a unit, integrating the leap day as a standard day. 365.25x4=1461. But that only divides by 3 and 481, even worse!
