Using the Dedicated API

This plugin provides a public API so you can use features like date and number conversion in other plugins and scripts (such as DataviewJS or Templater).

const pcApi = app.plugins.getPlugin("persian-calendar").api;

// Number conversion
pcApi.toEnNumber("۱۲۳ تست test"); // "123 تست test"
pcApi.toFaNumber("123 تست test"); // "۱۲۳ تست test"

// Solar Hijri date conversion
pcApi.jalaliToDate(1405, 9, 13); // Equivalent Gregorian date as Date object
pcApi.jalaliToGregorian(1405, 9, 13); // {gy: 2026, gm: 12, gd: 4}
pcApi.jalaliToHijri(1405, 9, 13); // (Iran basis) {hy: 1448, hm: 6, hd: 24}
pcApi.jalaliToHijri(1405, 9, 13, { base: "umalqura" }); // (Umm al-Qura basis) {hy: 1448, hm: 6, hd: 24}
pcApi.jalaliMonthName(9); // آذر (Azar)
pcApi.jalaliMonthName(9, "en"); // Azar
pcApi.seasonName(3); // پاییز (Autumn)
pcApi.seasonName(3, "en"); // Autumn

// Gregorian date conversion
pcApi.dateToGregorian(new Date()); // {gy, gm, gd}
pcApi.gregorianToDate(2026, 12, 4); // Date object
pcApi.gregorianToJalali(2026, 12, 4); // {jy: 1405, jm: 9, jd: 13}
pcApi.gregorianToHijri(2026, 12, 4); // (Iran) {hy: 1448, hm: 6, hd: 24}
pcApi.gregorianToHijri(2026, 12, 4, { base: "umalqura" }); // (Umm al-Qura) {hy: 1448, hm: 6, hd: 24}

// Lunar Hijri date conversion (Iran basis)
pcApi.hijriToDate(1448, 6, 24); // Date object
pcApi.hijriToGregorian(1448, 6, 24); // {gy: 2026, gm: 12, gd: 4}
pcApi.hijriToJalali(1448, 6, 24); // {jy: 1405, jm: 9, jd: 13}

// Lunar Hijri date conversion (Umm al-Qura basis)
pcApi.hijriToDate(1448, 6, 24, { base: "umalqura" }); // Date object
