• Help you how? What is your question? What do you want to have happen? – Makyen ♦ Commented Aug 26, 2016 at 6:58
• 3 because you can't just throw any old format that Chrome likes at IE and Firefox - Chrome handles dates differently (not more correct or less correct, just different) – Jaromanda X Commented Aug 26, 2016 at 6:59

• That does not look like a Date in either a RFC2822 / IETF date syntax (RFC2822 Section 3.3) format, e.g. "Mon, 25 Dec 1995 13:30:00 GMT", or a ISO 8601 format e.g. "2011-10-10" (just date) or "2011-10-10T14:48:00" (date and time). Read: Date.parse() (Firefox) – Makyen ♦ Commented Aug 26, 2016 at 7:09
• From what source are you getting the date? – Makyen ♦ Commented Aug 26, 2016 at 7:09

don't replace the '-' with '/', use whitespace instead.

var str = "05-Sep-2013 01:05:15 PM ";
console.log( Date.parse( str.replace(/-/g, ' ') ) );

that works for me in IE

have a look at w3schools - they're working with whitespaces :)

It is kind of odd, but a working solution for me is-

var str = "05-Sep-2013 01:05:15 PM ";
console.log( Date.parse( str.replace("-", " ") ) );

This format works with Chrome, Firefox and Safari:

const epochTime = Date.parse('2020/11/24 15:30')
