moment to validate date and time with custom format

I'm trying to use moment to check if the date/time presented is valid. I'm interested in validating dates in the following format:

10/10/2016 20:45

I've tried using this code, but the date is always considered invalid:

moment("10/10/2016 20:45", "dd/MM/YYYY HH:mm", true);

Any tips on what I'm doing wrong?

thanks.

Luis

You have 2045 in the input string, while you have HH:mm in the format, the problem is the :, change the input to 20:45 or the format to HHmm.

Moreover the token for day is the uppercase DD instead of the lowercase dd, see docs here.

Here a working example:

var m1 = moment("10/10/2016 2045", "dd/MM/YYYY HH:mm", true);
var m2 = moment("10/10/2016 2045", "DD/MM/YYYY HHmm", true);
var m3 = moment("10/10/2016 20:45", "DD/MM/YYYY HH:mm", true);
console.log(m1.isValid()); // false
console.log(m2.isValid()); // true
console.log(m3.isValid()); // true
