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. Under the late rule the Day pillar stays on the same day and the hour stem follows the next day. 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 your birth chart

A Western birth chart, or natal chart, is a map of the sky at the moment and place of your birth. It shows where the Sun, the Moon and the planets stood in the twelve signs of the zodiac and, if you know your birth time, which sign was rising on the eastern horizon and how the twelve houses fall.

How it is calculated

Fate Hall calculates the positions of ten celestial bodies with standard astronomical formulas, using your birth time converted to Universal Time with the historical time zone of your birthplace. The rising sign (Ascendant) and Midheaven come from the time and latitude, and the aspects — conjunctions, sextiles, squares, trines and oppositions — from the angles between planets. The calculations have been compared with published astronomical events to within a fraction of a degree.

Reading it well

Start with the "big three": the Sun sign for your core identity, the Moon sign for emotions, and the rising sign for how you meet the world. The East & West at a glance page shows your birth chart beside your BaZi chart. Our guides explain the Sun, Moon and Rising signs, the planets and houses and the five aspects.
