Which Signs Fall in January

In January, the sun travels through Capricorn from January 1 to January 19 and Aquarius from January 20 to January 31. Cusp dates at the beginning and end of each sign deserve a full chart calculation, since the exact moment of sign change varies by year and by hour.

Your sun is one tenth of your chart.
