  • 18:3518:35, 10 July 2017 diff hist +119 Twilight Added diagram of twilight at dawn. This makes clearer that there are two sets of "twilights", one at dawn and one at dusk. Because dawn came first in the caption/description of the first drawing, I put the dawn image first, followed by the dusk image.
  • 18:2418:24, 10 July 2017 diff hist −17 Dawn Updated image of twilight subcategories to use a relabeled and flopped version, that correctly labels dawn periods.
