Fix JavaScript date returning 1 instead of 31

Using Date with JavaScript might unexpectedly return the value 1 instead of 31:

// Incorrect:
var input = '2020-06-01';
var eventDate = new Date(input);
var result = eventDate.toLocaleString('default', { month: 'short' }) + ' ' + eventDate.getUTCDate() + ', ' + eventDate.getUTCFullYear()
console.log('result:', result);
