Javascript military date regular expression?

Question

Hi,

I haven't worked with reg expressions for some time now and I forget the syntax. I am trying to build an expression that will match on U.S. military style dates, ex ("24 Apr 08", "05 JUN 2006", "3 may 06"). I couldn't find an example anywhere on the internet. Does someone else have this?

Answer 1

Most dates in the Army are written YYYYMMDD

Example: August 13th 2008 would be - 20080813

Answer 2

The below regular expression should match any of the mentioned dates.

-----StartCode-----

/[0-9]{1,2}\s   [A-Za-z]{3}\s[0-9]{2}/

-----CodeEnd-----

Just remove the actual " " space after the first "\s".

The first part "[0-9]{1,2}" states that the first part should consist of the numbers 0-9, and that they should be between 1-2 characters long, the next "\s" matches a single white space, and finally we allow for normal word characters using "[A-Za-z]{3}", which states that the month should be using these, and be 3 characters long. Again we match "\s" a single white space, and "[0-9]{2}" sets the year to consist of numbers and be 2 characters long.

You can easily change this to match other date formats. I.E. YYYY/DD/MM
