TRY ANSWER WHAT · CAST BY TIME
Cast from a birth moment or right now — the lunar date is worked out for you.
Upper trigram = (lunar-year branch number + month + day) ÷ 8, keep the remainder; lower trigram = (that + hour number) ÷ 8, keep the remainder; moving line = the same sum ÷ 6, keep the remainder. The lunar conversion happens entirely in your browser.
🕐 Timezone: this page uses your device's timezone. Whatever local time you enter is the moment it casts for. To cast by Beijing time instead, convert your time to UTC+8 first. (The Almanac always uses Beijing time.)
An answer-book experience game, with the I Ching, Plum Blossom Numerology and the Chinese almanac as its reference.
Hexagram and line texts follow the received Yijing (I Ching); casting follows Shao Yong's Plum Blossom Numerology.
Hexagram and almanac calculations run in your browser; your input and results are not uploaded as part of computing them.
