Zodiac & Star Sign
Gives the Korean animal sign, the sexagenary year name and the star sign for a birth date.
Which animal year someone was born in is not settled by the solar date alone: one tradition changes the sign at lunar new year and another at 입춘, and for anyone born in January or early February the two disagree. This shows both, along with the 육십갑자 name of the year and the western star sign.
Date of birth
Leave it empty if you do not know it
띠 — animal of the year

황소자리 (Taurus)
Starts at
solar longitude 30°
the term 절기 곡우
The boundaries between signs are the instants the sun’s longitude passes each 30° — the same instants as the twelve 중기. The familiar fixed-date table rounds them, which is why a birthday on a boundary moves from year to year.
사주 — the four pillars (만세력)
| 시주 — hour | 일주 — day | 월주 — month | 년주 — year |
|---|---|---|---|
| — | 乙亥 | 辛巳 | 庚午 |
| hour unknown | 을해 | 신사 | 경오 |
| wood·water | metal·fire | metal·fire |
- The month pillar turns on a solar term, not on the first of the month. This date belongs to the month opened by 입하 (5/6 03:36).
- The year pillar counts from 입춘, so a birthday in January or early February can sit in a different year in the chart than on the calendar.
- With no birth time the hour pillar is left empty. Assuming midnight and writing 자시 is common, but that is choosing a pillar that changes every two hours at random.
A calendar computation. It draws the four pillars by the rules of the calendar; it does not interpret them.
Lunar birthday
음력
1990, month 4, day 16

How to use it
Enter the birth date
The solar date is enough — the lunar new year and the 입춘 instant for that year are computed from it.
Read both boundaries if you were born early in the year
Between 1 January and early February the animal sign depends on which boundary you count from, and the tool shows the answer under each rather than picking one.
Note that the 갑자 name is the year’s, not yours
갑진년 names a year in the sixty-year cycle. A full 사주 has four pillars — year, month, day and hour — and this gives the year one.
Common questions
Which boundary is the right one?
There is no single answer. Everyday usage in Korea follows lunar new year; 명리학 uses 입춘, because the pillars are built on the solar terms. Both are shown for that reason.
Is this a 사주 reading?
No. It reports the calendrical facts — the sign, the sexagenary year name, the star sign. It offers no interpretation of them.
Why does the star sign not match what I was told?
Star-sign date ranges vary by a day at the boundaries between sources, because the sun’s entry into a sign moves slightly from year to year. If your birthday is on a cusp, expect different answers from different tables.
