'man crontab' yields the following:
Code:
  crontab Entry Format
     A crontab file consists of lines of  six  fields  each.  The
     fields  are  separated by spaces or tabs. The first five are
     integer patterns that specify the following:

     minute (0-59),
     hour (0-23),
     day of the month (1-31),
     month of the year (1-12),
     day of the week (0-6 with 0=Sunday).

     Each of these patterns may be either an  asterisk   (meaning
     all legal values) or a list of elements separated by commas.
     An element is either a number or two numbers separated by  a
     minus  sign  (meaning  an  inclusive range). Notice that the
     specification of days may be made by two fields (day of  the
     month and day of the week). Both are adhered to if specified
     as a list of elements. See EXAMPLES.

Given the above:
Code:
0 12 * * 4 myScript

Your cron entry will be something like this:

Code:
0 12 * * 3 <scriptpath/scriptname>

0 = minutes (0-59)
12 = hour (0-23)
1st * = day of month (1-31)
2nd * = month (1-12)
3 = day of the week (0-6 where 0 = Sunday)

* denotes all values for that parameter will be used.

Hope that helps.
