Once I inspect the web page working fine but I opened in Incognito it doesn't work.
jQuery('#pickupdate').datetimepicker({
format: 'DD-MM-YYYY',
ignoreReadonly: true,
minDate: new Date().setHours(0,0,0,0)
});
jQuery('#dropoffdate').datetimepicker({
format: 'DD-MM-YYYY',
ignoreReadonly: true,
minDate: new Date().setHours(0,0,0,0),
useCurrent: false,
});
Are you missing a Document Ready?
