    The Moon is just barely big enough for total solar eclipses as is. If the lunar month was 4 days longer, the Moon would be (31.3/27.3)^(2/3)=9.54% farther away, and thus around 9.5% smaller. The maximum size ratio between the Moon and Sun is around 1.08 so it would never be large enough in the sky for a total eclipse.

      Okay, makes sense, but isn’t the distance between Earth and the moon uh… shri… grow… changing over time? So at some point in the past or future (or maybe even currently?), the distance would have been / would be the correct one for total eclipses.

          So just like we happen to live in that precise time where total eclipses are possible, the Logday people may have lived or may one day live in a time where the moon is the right distance. No need to pity those fuckers.
