Your eight characters
Four pairs of characters, one each for the year, month, day and hour you were born. Together they are your Bazi chart, also called the Four Pillars of Destiny.
Your five elements
How much Wood, Fire, Earth, Metal and Water your chart holds, and which one leads.
No birth time? That's fine
Leave the time out and you still get your year, month and day. The hour shows as unknown until you add it.
Common questions
What is a Bazi calculator?
It turns your date and time of birth into your Bazi chart: eight characters, two each for the year, month, day and hour you were born. Each character belongs to one of the five elements, which is where your element balance comes from.
Do I need my birth time?
No. Without it you get your year, month and day, and your elements are counted from those six characters. Add the time to fill in your hour and see all eight.
How is this different from my zodiac animal?
Your animal comes only from the year you were born, so everyone born that year shares it. Your Bazi chart also uses the month, day and hour, and the day says the most about you.
Why do calculators give different results?
Usually because of the hour. Your birth time falls into one of twelve two-hour blocks, and some calculators adjust it for where you were born (true solar time), which can move you into the next block. This calculator doesn't ask where you were born, so it uses your device's time zone. The 8 Signs app uses your exact birth place.
When does the year change in Bazi?
At the start of spring in the Chinese solar calendar, around 4 February: not on 1 January, and not at Chinese New Year. If you were born in January or early February, your Bazi year may be the one before.
Is my birthday saved?
No. It's used for this one calculation and never stored. There's no account and nothing to sign up for.
