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.
May 1 to 20: Taurus
Taurus is a earth sign ruled by Venus. People born on these dates tend to be reliable, patient and devoted, and can struggle with being stubborn and possessive. Read the full Taurus profile or see this month's Taurus horoscope.
May 21 to 31: Gemini
Gemini is a air sign ruled by Mercury. People born on these dates tend to be curious, adaptable and witty, and can struggle with being restless and indecisive. Read the full Gemini profile or see this month's Gemini horoscope.
May cusp dates
The shaded rows above (May 19, May 20, May 21 and May 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.
