How the Zodiac Compatibility Checker works
Your zodiac (sun) sign is determined from the standard Western tropical date ranges. Compatibility scores are calculated from the time-honoured astrological logic of elements (Fire, Earth, Air, Water), qualities (Cardinal, Fixed, Mutable) and polarities, so complementary signs score higher and clashing ones lower. Horoscopes are generated deterministically from your sign and the date, so the reading for a given day, week, month or year is stable and shareable. Kundli (marriage) matching uses the traditional Ashtakoota system, scoring the eight kootas out of 36 gunas from each person's Nakshatra and Rashi.
Everything is calculated in your browser, so your birth details stay private.
Tips & best practices
- Same-element pairs feel easy; opposite signs can be surprisingly magnetic.

These tools are for entertainment and self-reflection only. Astrology is not a science and cannot predict the future or determine real compatibility — relationships depend on the people in them. Horoscopes are generated from curated content by sign and date, not personal divination. Kundli matching follows the traditional Ashtakoota method as a guide; for any real decision, consult a qualified astrologer who reviews the full birth charts.
