Meihua Yishu Time Casting
This guide explains meihua yishu time casting: which inputs count, how they map to a hexagram and moving line, and whether OpenFate currently supports the method.
Time casting uses upper = year-branch number + lunar month + lunar day, lower = that sum + local hour-branch number, and moving line = the complete sum; upper and lower resolve modulo 8, the line modulo 6.
Classical plum-viewing arithmetic uses Chen year 5 + month 12 + day 17 = 34: remainder 2 gives Dui above. Add Shen hour 9 to get 43: remainder 3 gives Li below and remainder 1 gives the first moving line.
Declare the casting method before calculating. Record the question, permitted inputs, represented instant and timezone when relevant, pre-modulo totals, remainder mapping, line order, and methodology version.
How does Meihua Yishu Time Casting work?
Explain Meihua Yishu Time Casting, reproduce its check, and identify the point where evidence ends.
| Output | Declared total | Resolution |
|---|---|---|
| Upper trigram | year branch + lunar month + lunar day | mod 8; 0 → 8 |
| Lower trigram | upper total + local hour-branch number | mod 8; 0 → 8 |
| Moving line | upper total + local hour-branch number | mod 6; 0 → 6 |
How can you verify Meihua Yishu Time Casting?
Reproduce Meihua Yishu Time Casting from the recorded inputs, then label the result under the page's primary topic, “meihua yishu time casting.” Preserve the first reading and disconfirming evidence before revising it.
