Korean Wedding Traditions and Saju: Gunghap, Saju Danja and Choosing the Date
Long before the wedding hall and the photo shoot, a traditional Korean marriage began with two birth charts. Saju shaped who matched, when the wedding took place and what was sent between families. Here is how — and what is still practiced today.
Gunghap: Checking the Match
Gunghap (궁합) means comparing two people's saju to see how their charts fit together. Traditionally families did this before agreeing to a marriage, and many couples still check it today — usually for fun, sometimes for reassurance, and sometimes because a parent insists.
A gunghap reading looks at how the two Day Masters relate, how each chart's elements fill the other's gaps, and how the day branches — the “spouse palace” — interact. Modern readers treat it as a map of strengths and frictions, not a verdict.
Saju Danja: Sending the Birth Chart
Once the families agreed, the groom's side sent the saju danja (사주단자): the groom's year, month, day and hour of birth written on paper, folded and wrapped in cloth. It was a formal step — handing over a birth chart meant handing over trust.

Taegil: Choosing the Wedding Date
With both charts in hand, the bride's family chose the wedding date, a practice known as taegil (택일, choosing a day). The aim was a day whose energy suited both people's charts. Some couples still ask a saju reader to suggest dates, then pick the one that also fits the venue's calendar.
The Ham Box and the Wooden Wild Geese
Before the wedding, the groom's friends traditionally delivered the ham (함), a box of gifts for the bride's family, calling out as they arrived and playfully bargaining at the door.
At the ceremony itself, the groom presented a wooden wild goose (나무 기러기) to the bride's family. Wild geese were believed to keep one partner for life, so the carved bird stood for a lasting bond. Today carved mandarin ducks (원앙) are a popular wedding gift for the same reason.
Checking Your Gunghap Today
You do not need a marriage proposal to be curious. A modern gunghap compares your two charts element by element and shows where you naturally support each other and where you will need patience. It describes tendencies for reflection — it never decides a relationship or predicts what the other person will do.
