react-dates/esm/utils/isSameDay.js

A responsive and accessible date range picker component built with React

import moment from 'moment';
export default function isSameDay(a, b) {
  if (!moment.isMoment(a) || !moment.isMoment(b)) return false; // Compare least significant, most likely to change units first
  // Moment's isSame clones moment inputs and is a tad slow

  return a.date() === b.date() && a.month() === b.month() && a.year() === b.year();
}
