Degrees
via Tarot.com :
"For the Cardinal signs (Aries, Cancer, Libra and Capricorn), the critical degrees are 0, 13 and 26. For the Fixed signs (Taurus, Leo, Scorpio, Aquarius), they are 8-9 degrees and 21-22degrees. For the Mutable signs (Gemini, Virgo, Sagittarius, Pisces), they are 4 and 17 degrees. Do you have a planet or sensitive angle in your chart at any of these degrees? If so, you can expect more of a focus in that area of your life.
Furthermore, 0 degrees of any sign is considered a critical degree due to the karmic nature of being at the beginning of the sign. It is said that whatever planet or point is at 0 degrees will be in the early stages of learning lessons related to that point. Conversely, if a planet or point is at 29 degrees of any sign it is called an Anaretic Degree, and it symbolizes karmic completion related to that planet or points energy.It is possible that if a person has a birth chart with many planets or angles at the Anaretic Degree he or she is a very old soul. There may be a sense of urgency or need to finish up something related to that planet or points energies as well."

See "29" section.
"The Avatar degrees are 15° Taurus, Leo, Scorpio, and Aquarius. It's thought that these degrees of the Fixed signs bring forth resourcefulness, coincidences, and lucky accidents that can sometimes seem magical. An individual with a planet at the avatar degrees often becomes a "go-to" person who makes things happen."

( See Carl Jung's natal chart, 15° Taurus Moon if accurate. He was known for his interest in Paul Kammerer's "seriality" aka "synchronicity" aka meaningful coincidences. Jung was close to Freud who was a Taurus Sun. )

What degrees in astrology mean:
You can check below which Zodiac sign’s energy/quality is represented by each astrological degree. These are the essential qualities to add. Ifyou are familiar with the Zodiac Signs domains, you can add them too.
0 degree: Every 0 degree is like a double whammy of each sign. Interpret it as it doubles the energy of the Zodiac sign, where it is. (I.e., 0 degrees of Gemini, it is like a double Gemini energy.)
