I am not sure what is causing this issue, I'm assuming it's some dependency thing between date-holidays, date-holidays-parser, moment-timezone and moment.

Faced similar issue when tried to call destructured method returned from Holidays() constructor:

const { isHoliday } = new Holidays('US');
isHoliday(new Date(value));

Error:

Cannot read properties of undefined (reading '__timezone')
TypeError: Cannot read properties of undefined (reading '__timezone')
    at isHoliday (http://localhost:3000/static/js/bundle.js:424791:31)
    ...

Correct usage:

 const holidays = new Holidays('US');
 holidays.isHoliday(new Date(value));

There might be a binding issue somewhere in date-holidays code I guess.
