Gender
Time of birth

The Javanese day changes at sunset, so someone born after sunset takes the weton of the next day. Born after midnight? Enter the new calendar date and choose before sunset. If you enter a birth time, a time before 17:00 or from 19:00 decides this on its own, whatever is chosen.

Your birth date is only used for this calculation, and we do not store it.

What is BaZi?

BaZi, or the Four Pillars, is a Chinese tradition that reads a time of birth as four pairs of characters: year, month, day, and hour. The character on the day pillar, called the day master, is where a reading begins.

Years and months in BaZi change with the position of the sun, not the lunar calendar. Because of this, someone born around early February can have a BaZi sign that differs from their Lunar New Year sign.
