So, I am trying to come up with a Khajiit OC and was trying to create a lunar chart for 4E 202 (The year Skyrim the game takes place). Since Khajiit's form is dictated by the phases of the moons, I find that knowing the moons' exact phases on exact dates essential in creating a lore-friendly Khajiit character.

So far, I've been able to figure out that calendar of 4E 202 is identical to that of real-life year 2002. After observing the moons in my savegame in Skyrim, I observed twin full moons on April 17th or 17th of Rain's Hand in 4E 202. I am reasonably sure that Masser has 24 day cycle, meaning it takes 12 days for the red moon to go from full moon to new moon, and vice versa. HOWEVER, I have been unable to properly identify Secunda's lunar cycles due to its erratic appearances and smaller size. Can someone, hopefully someone working in Bethesda's lore department, tell me what is the exact length of the cycles for Masser and Secunda? Thank you.
