Thai Astrology

Thai Astrology (โหราศาสตร์ไทย) is a TypeScript library that implements classical Thai astrological calculations. It converts birth details into the 12-channel chart lakna, Tanuseth, planetary positions without relying on runtime dependencies.

Install

npm install thai-astrology

Usage

import {
  formatChannelOutputs,
  generateThaiAstrologyChart,
} from "thai-astrology"

const chart = generateThaiAstrologyChart({
  day: 15,
  monthTh: 9,
  yearBe: 2566, // 2023 in BCE 
  hour: 14,
  minute: 45,
  province: "กรุงเทพมหานคร", // Bangkok
})

console.log(formatChannelOutputs(chart))
console.log(formatChannelOutputs(chart, "thai"))
console.log(formatChannelOutputs(chart, "arabic"))
console.log(chart.sunPosition) 

For BCE dates, supply yearBc instead of yearBe.

Example output:

[ '58', '0',  '9',  '6', '14', '23', '',   '', 'ลั',  '',   '7*', '' ]

[ '๕๘', '๐',  '๙',  '๖', '๑๔', '๒๓', '',   '', 'ลั',  '',   '๗*', '' ]

[ '58', '0',  '9',  '6', '14', '23', '',   '', 'ลั',  '',   '7*', '' ]

[ 27, 29 ]
