Saju basics

Quick answers before you start.

What is Saju (Korean Four Pillars of Destiny)?

Saju is the traditional Korean reading of the "four pillars" of your birth — year, month, day and hour. Each pillar is written with two characters, giving eight in total. Bujasaju calculates these eight characters and explains your natural tendencies and life rhythm in plain English.

What are the Five Elements in Saju?

The Five Elements are Wood, Fire, Earth, Metal and Water. Each of the eight characters belongs to one element, and a reading looks at which elements are strong or weak and whether they support or restrain one another.

What can I see for free?

A daily tarot card (once a day), the 12 zodiac animal fortunes, and a preview of the 2027 Tojeong Bigyeol year reading (your year's sign and January) are free. Asking questions about your own Saju is a paid service charged per message.

What if I don't know my birth time?

Choose "Unknown" for the birth time and we read your chart from three pillars — year, month and day — without the hour pillar. We never fill in a guessed time such as noon.

Will the same birth date and time always give the same result?

Yes. Your eight characters and five-element balance are calculated the same way every time for the same details, and the reading is built on those calculated values.

How is my Saju calculated?

Years and months change at the solar terms (such as Ipchun, the start of spring), not on the 1st of the calendar month. Your birth time is adjusted to the longitude of your birthplace, and births during Korea's past daylight-saving periods are corrected by that hour as well.

How do you handle my personal data?
