Under the tropical zodiac, the Sun enters Capricorn by definition at the moment of winter solstice, or roughly at December 22, and leaves it around January 19.
Capricorn is content to work within the social order in which it finds itself and seeks success therein. A great sense of responsibility and a determination to complete any project once started. Seeks tangible results.
