Dates use the tropical zodiac. "Part of sign" splits each sign into three parts of about ten days (decans), ruled by the sign itself and then the next two signs of the same element.
March 1 to 20: Pisces
Pisces is a water sign ruled by Neptune. People born on these dates tend to be compassionate, artistic and intuitive, and can struggle with being escapist and over-trusting. Read the full Pisces profile or see this month's Pisces horoscope.
March 21 to 31: Aries
Aries is a fire sign ruled by Mars. People born on these dates tend to be courageous, determined and energetic, and can struggle with being impatient and impulsive. Read the full Aries profile or see this month's Aries horoscope.
March cusp dates
The shaded rows above (March 19, March 20, March 21 and March 22) sit next to a change of sign. The Sun moves into the next sign at a slightly different hour each year, so on these days the sign you see in a table may not match your own chart. Your birth time and place settle it.
