The Day Out of Time falls on the day before the Heliacal Rising of Sirius. In Egypt the Day Out of Time is on July 25 as the Heliacal Rising of Sirius is on July 26. So it was sort of like New Years Eve to the Egyptians. Its the day that doesn’t exist as it is “out(side) of time”. How so? Well, you have to understand the Moon calendar.
There are 364 days(13 months x 28 days = 364) in the Moon calendar, meaning the 365th day doesn’t exist. The Day out of Time is the 365th day or the day between the two calendars. The Heliacal Rising of Sirius occurs across a range of days depending on where you live. In the Egyptian calendar, it is July 26 so that’s why the Day Out of Time is on the 25th. But for instance in Southern California, the Heliacal Rising of Sirius isn’t until sometime after the 26th. That doesn’t mean that you can’t celebrate it on July 25.
Embrace the spirit of the day. It doesn’t exist so consider it a day to do whatever you want. Get outside, enjoy life, don’t worry about Earthly things like paying bills, worrying about anything, etc. Just enjoy the day. The other thing that will help to make it even more interesting for you is to not even worry about time. Remember the day doesn’t exist so why should time exist? Live like there is no time and just base your day on your feelings.
