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 the Maya calendar

The ancient Maya kept a 260-day sacred calendar, the Tzolk’in, alongside their 365-day solar year. Each day combines one of 13 numbers (tones) with one of 20 day signs, such as Imix (crocodile) or Ajaw (sun), to make 260 unique day names, or kin.

How it is calculated

Fate Hall counts days from the widely used GMT correlation between the Maya Long Count and our calendar, so your birth kin and today’s kin are exact. The page shows your day sign and tone, today’s kin, and how they relate, including the "color family" of day signs.

A note on tradition

Day-keepers in highland Guatemala still use the 260-day count today. Many popular "galactic" interpretations are modern inventions; Fate Hall keeps to the traditional day signs and notes where meanings are modern.

Common question

Why does my kin differ from some websites? Several correlations between the Maya and Western calendars exist, and some popular systems skip leap days. Fate Hall uses the standard GMT correlation followed by most archaeologists and by traditional day-keepers.
