When Pope Gregory XIII briefly shortened the light-year in 1582, it led to navigational chaos and the loss of several Papal starships.

    Hmmm now that I think about this a light year would be (should be) based on an average year, not what we observe in any given year.

    365.2425 days. Different searches give different results but that’s what I’m going with.

      idk, it feels more intuitive for it to be based on the mode (most common) year length (365) instead of the average year length (365.2425).

        No, years divisible by 100 aren’t leap years, except if they’re also divisible by 400.

        They skip leap years every now and then. And then skip the skip. Etc. The rotation of the earth around the sun and the spin of the earth on its axis simply don’t line up into a nice number.

          Oh okay. Yeah I only have that rule of “every 4 years” in my head. I did some other programming exercise way back where we had some other rule, but I was thinking that it would end up being the same.

    Just wondering, but do people actually find xkcd funny? Are these comics supposed to be funny?
