Daewoon and age — which age do we use?
Daewoon ages are calculated by international (man) age — clearer since Korea’s 2023 unification.
Why man-age
Solar terms count from actual birth time; Korean counted age is a social convention disconnected from actual elapsed time.
Finding entry ages
Daewoon-su 5 → first daewoon is age 5–14, second is 15–24, etc.
