Ancient Egyptian astrology is not the same astrology we use today, although modern astrology is rooted in the ancient Egyptian calendar system...
This is probably the first recorded battle in ancient Egypt. This battle marks the beginning of the dynastic period in approx. 3100 BC, with King Narmer waging war on the separate regions and combining them to form a unified Egypt with himself as its first Pharaoh.
So basically your star-sign has a first, second and third decante.
If you were born in the first 10 days of your sign, it would mean you are of the first decante of whatever that sign is.
The ancient Egyptian Zodiac is also divided like that, and some signs are quite similar. Take a look at it here.
So if you were born on the 30th of July, you would be a Leo of the first decante. Although a third decante Leo would share your sign's characteristics, there would be slight differences in those characteristics.
The other interesting connection is that your star-sign is represented by a Glyph!
There are star charts dating back to 4200 BC made by ancient Egyptian astrologers still available today. In fact, our great Imhotepmade one of the first horoscopes, all the way back in 2767 BC.
I'm sure you have already made the connection in your head before reading it now, but I have to mention it: Ancient Egyptian astrology is, of course, linked to ancient Egyptian Religion. The astrologers were actually priests. They invented the calendar to measure time, mostly out of a need to understand the cycle of the Nile. This was necessary in order to ensure sufficient crops.
They also predicted famines, moon and star movements, eclipses, and other important events. They mapped out the stars and divided the sky into 36 sections, each one a decante. Then they grouped 3decantes together to form 1 sign - and that's how we have 12 parts or signs.
Each part was assigned its own name and form, and also 3 stars.
A lover and believer of astrology was our great King Ramesses II. His temple at Abu-Simbel is a testament of the greatness of ancient Egyptian astronomy as well as engineering. The temple is built so that the sun would shine in on the statues of 3 gods inside - once on the equinox on February 22 and once on the equinox on October 22. The fourth god was Ptah, who the sun did not reach as he is a god of the underworld.
His mummy was wrapped and placed inside a sarcophagus covered in astrological symbols.
Another amazing example is that of King Ramesses VI. There is a star map, also called a star clock, in his tomb of a seated man. This map can be used to map the journey of the stars for each hour of the night, through the whole year!
The ancient Egyptian/Greek philosophy calledHermeticism is a beautiful set of religious beliefs that describes the human being as a reflection of the entire cosmos (or universe). Have you heard this phrase before: "as above, so below"? I'm sure you've also seen the symbol for it as well, shown here on the right.
There is a connection with this ancient science and modern astrology... Your particular sign is associated with a specific part of the human body.
For example, Sagittarius is associated with the thighs (denoting the sign's love of freedom, movement and travel). What this implies is that the entire Zodiac is contained in your body!
Sadly there isn't that much information on the characteristics of the signs or predictions in ancient Egyptian astrology, so I can't really delve into the subject deeply.
Although we don't use the same signs anymore, there is one ancient Egyptian system which is very similar to what we do use in modern astrology. Here's the comparison:
There are more Egyptian astrology horoscope interpretations available, but they are not very factual nor reliable. You can take a look at them here while keeping in mind it's just for fun.
