Thai couple compatibility by birthday
Old Thai formulas read a couple from the weekdays they were born on (Sunday = 1 to Saturday = 7) and from their Thai year animals (Rat = 1 to Pig = 12): add the numbers, multiply, divide by 7 and read the remainder. Six Thai readings are gathered here.
Translated and combined from six Thai pages. Texts were condensed; references to one partner dying first and to sexual matters were rewritten, and the Thai “man/woman” order is not needed because these formulas are symmetric, except the fortune title, which reads the first person's animal first.
