Question

I want to convert a time string say ’12:05 PM’ into a datetime using Date.Parse in Javascript.
When I pass in a value of say 12:05 PM or 12:10 PM or … or 12:55 PM the value returned by startTime below is null, i.e. startTime = null

But when I pass in values of 1:00 PM, 1:05 PM, 1:10 PM, 12:00 AM,…,12:00 PM it works fine
returning me a Date with the time included.

This is the code line causing an issue:

var startTime = Date.parse($("#<%= StartTime.ClientID %>").val());  //code causing the issue
    

And StartTime is a textbox.

I am writing the above code in client/html in an ASP.NET application on the web form.

If you’re using date.js then try (as per test case here)

Date.parseExact("12:05 PM", "hh:mm tt");

This should also pick up if you’ve loaded the library correctly.
