JAVASCRIPT – MomentJs date and time validation

A good way to validate date and time in javascrit is with momentJs:

<script src=""></script>


const allPossibleFormats = [
  'D MMMM YYYY HH:mm',
  'DD.MM.YYYY HH:mm',
  'DD/MM/YYYY HH:mm:ss',
  'MM-DD-YYYY HH:mm:ss',
  'MM/DD/YYYY HH:mm:ss',
  'YYYY-DD-MM HH:mm:ss',
  'YYYY-MM-DD HH:mm',
  'YYYY-MM-DD HH:mm:ss',
  'YYYY-MM-DD h:mm:ss A',
  'ddd, MMM D YYYY LT',
  'dddd D MMMM YYYY HH:mm',
  'dddd, MMMM Do YYYY LT'

moment('Chicago Illinois 46702', allPossibleFormats, true).isValid(); // false
moment('18/01/1944', allPossibleFormats, true).isValid(); // true
moment('22-10-2020', allPossibleFormats, true).isValid(); // true
moment('1944-01-18 12:00:00', allPossibleFormats, true).isValid(); // true
moment('2001-01-01 00:00:00', allPossibleFormats, true).isValid(); // true
moment('2001-01', allPossibleFormats, true).isValid(); // true
