dates_comparing.js

const _compareDates = (date1, date2) => {
  date2.setHours(date1.getHours());
  date2.setMinutes(date1.getMinutes());
  date2.setSeconds(date1.getSeconds());
  date2.setMilliseconds(date1.getMilliseconds());

  return date2 - date1;
};

const isDatePast = (now, date) => _compareDates(now, date) < 0;

const isDateFuture = (now, date) => _compareDates(now, date) > 0;

const areDatesEqual = (now, date) => _compareDates(now, date) === 0;
