Holidays

Opt-in date-holidays for isHoliday and skipHolidays.

date-holidays is an optional peer: it is not in @koalarx/utils dependencies, so core-only consumers are not forced to install holiday datasets.

  1. npm install date-holidays in your project
  2. import '@koalarx/utils/holidays' in bootstrap

Without the import, isHoliday / skipHolidays throw.

typescript 
import { KlDate, isHoliday } from '@koalarx/utils/KlDate';
import '@koalarx/utils/holidays';

isHoliday(new KlDate('2020-01-01'), 'BR');
