January zodiac signs
January has two zodiac signs: Capricorn and then Aquarius. From 1950 to 2010, the Sun entered Aquarius on January 19 in 2 years, January 20 in 55 years and January 21 in 4 years, in UTC.
January birthdays belong to two very different signs, and both are read as serious about something. Capricorn's side of the month is read as patient and ambitious, the people who keep a plan going in the coldest weeks of the northern year. Aquarius, from around the twentieth, is read as independent and a little contrary, happiest with a friend who argues back. In love, the first asks whether you'll stay and the second asks whether you'll let them be.

How these dates are worked out
We take each position from astronomy-engine, the open-source astronomy library behind our birth charts, at noon UTC on the date, in the tropical zodiac our charts use. Changes of sign and New and Full Moons are searched to the minute in UTC, and eclipses are dated by the moment they peak. If you were born close to a change, your birth time and place decide. How we calculate the sky shows the checks.
