I don’t know my birth time

Time basisClocks follow your time zone’s standard meridian, so the Sun at your birthplace can run minutes ahead of or behind the clock. Longitude correction fixes that offset; true solar time also adds the seasonal equation of time (±16 min). Rat-hour rule (23:00–00:59)Only matters if you were born between 23:00 and 23:59. Most modern practitioners use the early Rat-hour rule.

Why does birth time need correcting? ▾

Solar time, not clock time. In BaZi the hour pillar, and the day pillar near midnight, follow where the Sun actually was. Clock time is set for a whole time zone, so at your birthplace the Sun may cross the meridian earlier or later than clock noon. We use the longitude of your birthplace to correct for that, and can also add the equation of time (from −14 min in February to +16 min in November).

Daylight saving time is taken from your browser’s time zone database for the birth date, so summer-time births are converted to standard time automatically.

Whichever basis you pick, the “Pillars under each time basis” panel shows every combination side by side. If they differ, choose the one closest to the time on your birth certificate.

About Tojeong Bigyeol

Tojeong Bigyeol (土亭秘訣) is a Korean book of yearly fortunes traditionally attributed to the 16th-century scholar Yi Ji-ham, known as Tojeong. Families have consulted it at the start of the lunar new year for centuries, and it remains one of the best-known fortune traditions in Korea.

How it is calculated

The reading comes from three numbers built from your lunar birthday and your age that year, counted the traditional Korean way (one year old at birth). The year’s celestial stem and branch give the upper number, the length of your birth month gives the middle number, and your lunar birth day gives the lower one. Together they point to one of 144 verses, each with an overall message and twelve short monthly verses. Because the book follows the lunar year, a new reading begins at Lunar New Year (Seollal).

Reading it well

The verses are poetic and often use images from farming and nature. Read them as a mood for the year rather than a literal prediction; many families enjoy comparing their verses together at the new year.
