How to validate if a string is a valid date in js

Question

This question already has an answer here:

• Check if a string is a date value 20 answers

I have string field which is used to get different values. Some of the values received are dates. Now I need to check if value received is date or not? The date received can be in different formats again.

I tried Date.parse(), it works if format is dd-mm-yyyy hh:mm, but I have some dates received in like (26/05/2015 06:20:57 +00:00).

How do I compare if string is valid date or not?

If Date.parse() is not enough for you - but it may be enough - see the documentation at:

• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/parse

then you may try:

• Moment.js

It is a library to parse, validate, manipulate, and display dates in JavaScript, that has a much richer API than the standard JavaScript date handling functions.
