/**
 * A `HDate` represents a Hebrew calendar date.
 *
 * An instance of this class encapsulates a date in the Hebrew calendar system.
 * It consists of a year, month, and day, without any associated time or location data.
 * The Hebrew calendar is a lunisolar calendar, meaning it is based on both lunar and solar cycles.
 *
 * A Hebrew date internally stores three numbers:
 * - year: The Hebrew year (1-9999). Counted from the traditional Hebrew date of creation (3761 BCE in the Gregorian calendar)
 * - month: The Hebrew month (1-13). Month 1 is Nisan, month 7 is Tishrei. There are 12 months in a regular year and 13 months in a leap year.
 * - day: The day of the month (1-30)
 *
 * This class uses Rata Die to convert between the Hebrew and Gregorian calendars.
 *
 * To calculate times of day, use `Zmanim` class from `@hebcal/core`
 * @see {@link https://en.wikipedia.org/wiki/Rata_Die | Rata Die}
 * @see {@link https://hebcal.github.io/api/core/classes/Zmanim.html | Zmanim}
