basename

• basename(): string

  Returns a simplified (untranslated) description for this event, suitable for grouping related events under a single name.

  For example, HolidayEvent strips qualifiers so that "Erev Pesach" → "Pesach" and "Sukkot III (CH''M)" → "Sukkot". For many events the basename and the event description are identical.

  Returns string

  Example

  import {HolidayEvent, HDate, months, flags} from '@hebcal/core';
  const ev = new HolidayEvent(
    new HDate(14, months.NISAN, 5784), 'Erev Pesach', flags.EREV);
  ev.getDesc();    // 'Erev Pesach'
  ev.basename();   // 'Pesach'
  Copy

getCategories

• getCategories(): string[]

  Returns an array of category strings classifying this event, derived from its flags bitmask. The first element is the broad category (e.g. 'holiday', 'roshchodesh', 'parashat', 'omer'), followed by zero or more refinements (e.g. 'major', 'minor', 'fast').

  Returns ['unknown'] if no flag maps to a known category.

  Returns string[]

  Example

  import {Event, HDate, flags} from '@hebcal/core';
  new Event(new HDate(10, 'Tishrei', 5784), 'Yom Kippur', flags.MAJOR_FAST)
    .getCategories(); // ['holiday', 'major', 'fast']
  new Event(new HDate(1, 'Shvat', 5784), 'Rosh Chodesh Sh\'vat', flags.ROSH_CHODESH)
    .getCategories(); // ['roshchodesh']
  Copy
