[**dayjs-hijri-plus v1.0.1**](../README.md) *** [dayjs-hijri-plus](../README.md) / default # Variable: default > `const` **default**: `PluginFunc` Defined in: [src/index.ts:164](https://github.com/acamarata/dayjs-hijri-plus/blob/599c7481510f5ea625b79c98a7030b9c8d90e4f7/src/index.ts#L164) Day.js plugin that adds Hijri calendar support. Register once with `dayjs.extend(hijriPlugin)`. After that, all `dayjs()` instances expose `.toHijri()`, `.isValidHijri()`, `.hijriYear()`, `.hijriMonth()`, `.hijriDay()`, and `.formatHijri()`. The static factory `dayjs.fromHijri(hy, hm, hd)` is also added. All calendar arithmetic is delegated to hijri-core. This plugin adds no conversion logic of its own. ## Example ```ts import dayjs from 'dayjs'; import hijriPlugin from 'dayjs-hijri-plus'; dayjs.extend(hijriPlugin); dayjs('2023-03-23').toHijri(); // => { hy: 1444, hm: 9, hd: 1 } ```
