Just some of the research I have compiled to help me learn more about the different degrees within a birth chart.
There are 12 signs within the zodiac wheel, each sign is made up of 3 sets of decans that are equal to 30 degrees.
1st - 0 - 9 degrees 59 minutes, 59 seconds
2nd - 10 - 19 degrees 59 minutes, 59 seconds
3rd - 20 - 29 degrees 59 minutes, 59 seconds
Each decan is equivalent to 10 days and there are some differences in how different signs present themselves depending on which decan they fall into.
Here are some helpful links for more information on decans: https://thothblogs.blogspot.com/2018/12/decan-wheel.html https://beau-life.com/blogs/beau-blog/a-quick-and-easy-explanation-of-decans-or-decantes-what-they-mean
Some different interpretations of the degrees:
If a planet is at 0 degrees in a chart it is indicative of new karma, you may not have experienced it in previous life times or are restarting with new challenges, the planet and the sign are undiluted in nature - the light and the dark.
The 29th degree is called an anaretic degree and symbolises karmic completion, plus possible long term fame in the areas dictated by the sign, planet and house that it is in.
Other indicators of fame are the 5th (short term) and the 17th (long term)
If a planet is between the 14th and 16th degree you will find that you deal with the signs specific issues. If you have a planet at the 15th degree in any of the fixed signs (Taurus, Leo, Aquarius and Scorpio) you will be blessed with resourcefulness, strange coincidences that appear as lucky accidents that seem magical and you may be considered the go to person by your inner circle. This is called an Avatar degree.
There is a something called the Aries point, this is when a planet is at 0 degrees in any of the cardinal signs (Aries, Libra, Cancer, Capricorn). This symbolises recognition - not necessarily celebrity - within your chosen field. It reveals potential for individuals to make an impact and be recognised through their Aries point gift. For example someone with Mercury at 0 degrees in Libra might be an excellent communicator and be recognised as such.
