Possible return values for (new Date()).toDateString() in JavaScript?

Question

The return value for (new Date()).toDateString() is "Mon Oct 08 2012". However I can't find ANY documentation anywhere for what the abbreviations for the rest of the days of the week and months are. Are they all just 3 character abbreviations? I'm trying to write a regex.

+1million points for someone who can find the documentation, or even the source code?

Answer 1

Three letter abbreviations with the first letter upper case.

• Months: Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec
• Days: Sun, Mon, Tue, Wed, Thu, Fri, Sat

However, you may want to look into Date.Parse() instead of using a regular expression to parse the date string, depending on what you're doing anyway.

EDIT: Beware that that Date.Parse() is fairly browser dependent. Check out Why does Date.parse give incorrect results?
