Mars makes this stretch of the sign more assertive and action-minded — these are people who move first and think about the details on the way.

What zodiac sign is January 2?
January 2 falls in Capricorn, which runs from December 22 to January 19 in the tropical zodiac. The Sun changes sign at a slightly different moment each year, so the boundary can fall a day or so either side of these dates. If you were born close to the edge, your birth year, time and place decide it.
Is January 2 a cusp birthday?
Not by the usual definition, which counts the first and last couple of days of a sign. January 2 is day 12 of Capricorn season, so it is normally read as a clear Capricorn birthday.
Which decan is January 2?
January 2 is in the second decan of Capricorn (January 1–10). In the traditional Chaldean system this decan is ruled by Mars, which astrologers say adds its own flavour to Capricorn. Some modern astrologers assign decan rulers by element instead, which gives different planets, and decans are strictly 10° slices of the zodiac, so the date range is approximate.
What are the birthstone and flower for January?
The modern birthstone for January is Garnet and the birth flower is the carnation. These come from calendar tradition rather than astrology, and the lists vary by country and source.
