I agree with vbe's solution like we can run script on each Sunday and check either it is 3rd Sunday or not.
Following code may help you to get the 3rd Sunday with explaination.
Logic behind the code is if we need to get any 3rd occurance of a day(Sunday in this case) in a month it should come in 5th line of command cal output, but in case a month's starting day is not Sunday so number of fields NF will be less than 7 then. So by condition NF<7 we are checking the same and assigning a value of variable i. Now if number of fields are less than 7 means 1st day of a month is not Sunday so we need to jump to next line which is 6th line of command cal so we are doing here NR==(5+i) and checking if condition is true and printing it.
Hope this helps.
Thanks,
R. Singh

cal
CAL(1) BSD General Commands Manual CAL(1)NAME
cal -- displays a calendar
SYNOPSIS
cal [-smjy13] [[month] year]
DESCRIPTION
Cal displays a simple calendar. If arguments are not specified, the current month is displayed. The options are as follows:
-1 Display single month output. (This is the default.)
-3 Display prev/current/next month output.
-s Display Sunday as the first day of the week. (This is the default.)
-m Display Monday as the first day of the week.
-j Display Julian dates (days one-based, numbered from January 1).
-y Display a calendar for the current year.
A single parameter specifies the year (1 - 9999) to be displayed; note the year must be fully specified: ``cal 89'' will not display a calen-
dar for 1989. Two parameters denote the month (1 - 12) and year. If no parameters are specified, the current month's calendar is displayed.
A year starts on Jan 1.
The Gregorian Reformation is assumed to have occurred in 1752 on the 3rd of September. By this time, most countries had recognized the ref-
ormation (although a few did not recognize it until the early 1900's.) Ten days following that date were eliminated by the reformation, so
the calendar for that month is a bit unusual.
HISTORY
A cal command appeared in Version 6 AT&T UNIX.
OTHER VERSIONS
Several much more elaborate versions of this program exist, with support for colors, holidays, birthdays, reminders and appointments, etc.
For example, try the cal from http://home.sprynet.com/~cbagwell/projects.html or GNU gcal.
