Aah-te-Huti is the ancient Egyptian moon god.
Aah was one of the earliest ancient Egyptian deities and was in charge of the ancient lunar year (12 to 13 months of 28 days each). By the Pharaonic period, the Egyptian months were organized as twelve 30-day months, each with three ten-day weeks, for a total of 260 days a year. The months did not have individual names until the New Kingdom. Months were grouped into three four-month sseasons. The extra five days of the 365-day year were considered outside of the normal year and not a part of any month.
The ancient Egyptian hieroglyph for month was a crescent moon (the first visible crescent after the New Moon) over the symbol for star.
After the early period of Kemet, Aah faded in popularity and his duties became somewhat shadowy. Aah is quoted in the Book of Coming Forth into the Day (often called the Egyptian Book of the Dead) as saying “I am the moon-god Aah, the dweller among the gods.”
Aah was sometimes depicted with the sun disk on top of the moon crescent.
