Well, not long now. I mark this time as my Wep Ron Pet. I know many modern Kemetics use the first week of August or even September as that is when Sothis rises now in most places. However for me, as far as I know from Old Kingdom and before the Nile flood, summer solstice and Sothis all occurred around the same time. With one of those (the solstice) noticeable to me then I take that time as the start of the five days.
I tend to mark it at night time as living at the bottom of a valley my view of the sun is obscured in the morning but sets in view. I will be putting offerings up of home brew mead and wine, as well as making a number of foods that are possibly of ancient origin.
Does anyone else mark the solstice?
