What Month Is Aquarius?

Aquarius covers two months. Aquarius season starts around January 20 and ends around February 18, so a January Aquarius has a birthday in the last third of January, and a February Aquarius has a birthday in the first two and a half weeks of February.

Born on January 19, 20, or February 18, 19? You Might Be on a Cusp

The Sun doesn't move into a new sign at the same minute every year, so the start and end of Aquarius season can shift by about a day. If your birthday is right at the edge, you may be on a cusp:

Capricorn-Aquarius cusp (about January 16–23): Capricorn's discipline and ambition meet Aquarius's originality.
Aquarius-Pisces cusp (about February 15–21): Aquarius's big ideas meet Pisces's imagination and empathy.

To know your exact sign, check the year and time you were born, since the Sun's entry into Aquarius varies slightly from year to year.
