# @hebcal/core

Hebcal is a perpetual Jewish Calendar. This library converts between

Hebrew and Gregorian dates, and generates lists of Jewish holidays for

any year (past, present or future).  Shabbat and holiday candle

lighting and havdalah times are approximated based on location. Torah

readings (Parashat HaShavua), Daf Yomi, and counting of the Omer can

also be specified. Hebcal also includes algorithms to calculate

yahrzeits, birthdays and anniversaries.

[![Build Status](https://github.com/hebcal/hebcal-es6/actions/workflows/node.js.yml/badge.svg)](https://github.com/hebcal/hebcal-es6/actions/workflows/node.js.yml)

Hebcal was created in 1994 by Danny Sadinoff as a Unix/Linux program

written in C, inspired by similar functionality written in Emacs

Lisp. The initial JavaScript port was released in 2014 by Eyal

Schachter (age 15). This ECMAScript 2015 implementation was released

in 2020 by Michael J. Radwin. `@hebcal/core` targets both

browser-based JavaScript and server-side Node.js.

Many users of this library will utilize the [HebrewCalendar](https://hebcal.github.io/api/core/classes/HebrewCalendar.html)

and [HDate](https://hebcal.github.io/api/hdate/classes/HDate.html) interfaces.

## Installation

```bash

$ npm install @hebcal/core
