Sun Sign Calculator
A Sun Sign Calculator is an astrology tool designed to help users find their zodiac sun sign based on their date of birth.

Formula and Logic Used
A Sun Sign Calculator does not use a traditional arithmetic formula. Instead, it follows zodiac date mapping.
The logic is:
Birth Date → Compare With Zodiac Date Range → Return Sun Sign
For example:
If birth date is August 10:
August 10 falls between July 23 and August 22.
Therefore:
Sun Sign = Leo
For advanced accuracy near cusp dates, birth time and birth location may be considered.
