Check Our Compatibility — Free ✦Works for couples, crushes, friends & co-founders
Yours and theirs — birth date, time (optional), and gender. A partner, a crush, a friend, a co-founder: any two charts work.
Each person's Four Pillars (사주팔자) is computed separately, then the two charts are placed side by side — the way 궁합 has been read for centuries.
Day Master chemistry, element support and clash dynamics, and what each of you brings to the pairing — explained in plain English.
Gunghap is the Korean tradition of reading two saju charts together to see how they interact — classically consulted before marriage, and still widely used today for partners, family, and business relationships. It compares Day Masters, elements, and branch relationships between the two charts.
Creating both charts and seeing your Day Master pairing is free. The full compatibility reading — score, chemistry deep-dive, and how each side experiences the other — is a one-time $2.99 unlock. No subscription.
No. An unknown birth time still yields the Year, Month, and Day pillars for that person — enough for a meaningful compatibility reading. Birth hours sharpen the inner-world comparison when you have them.
Yes. Gunghap is not only romantic — the same chart dynamics describe friendship, family, and working relationships. The reading covers how the two charts communicate, support, and challenge each other in any relationship.
Classical saju describes characteristic pairings between the 10 Day Masters — some harmonize through the productive element cycle, others transform through 합 (combination). You can browse all 55 pairings free in our Day Master compatibility guide, or calculate a real two-chart reading for specific people.
