Your sun sign is where the Sun was on the day you were born. Instead of a fixed table of dates, this calculator works out the Sun's actual position for each birth date, so birthdays on the cusp (around the 19th–23rd of each month) get the right sign for that year.
Then it shows your sun sign compatibility — overall, plus love, intimacy, friendship, communication and trust.
