What is a sign?

A sign is 30 degrees, one twelfth of a full circle. The name comes from astrology and early astronomy, where the band of sky the Sun appears to travel through is divided into twelve signs of the zodiac.

The Sun moves through roughly one sign each month, which is how the unit ended up tied to the calendar. Today it appears mainly in historical and astrological calculations rather than in engineering work.
