January Zodiac Sign: Capricorn or Aquarius?
The January zodiac signs are Capricorn (approximately January 1–19) and Aquarius (approximately January 20–31). Birthdays near the change need a calculation using the birth year and time.
A January 1 birthday is normally Capricorn. The calendar year starts partway through that sign; Aquarius comes later in the month.

January 19 or 20: Capricorn or Aquarius?
The familiar January 20 cutoff is a calendar shorthand. The Sun enters Aquarius at a particular moment, and that moment falls on different local dates in different years and time zones. If your birthday is around January 19–21, use your birth year, time, and place before deciding which profile to read.

Our free birth-chart calculator uses your full birth date, local birth time, and birthplace. If you do not know the time and were born near the sign change, treat the Sun-sign result as uncertain. Choosing a default time cannot settle a boundary birthday.

January 1 is a calendar milestone, not the start of the tropical zodiac. That zodiac begins with Aries at the March equinox. A New Year birthday is normally Capricorn, and sharing a calendar month with Aquarius does not give someone two Sun signs.
Questions about January birthdays
What zodiac sign is January 1?
January 1 is normally Capricorn in the tropical zodiac. It is well away from the Capricorn–Aquarius transition, so a conventional date guide is sufficient for this basic Sun-sign question.
Is January 25 Capricorn or Aquarius?
January 25 normally falls in Aquarius. For a fuller reading, first confirm the Sun sign, then use the birth chart to find the Moon and rising signs rather than assuming all three are Aquarius.
