Assuming you don't actually need any of the intermediate stuff, this calculates it directly:

#!/usr/bin/perl -slw use strict; use warnings; use Time::Local; use Test::More "no_plan"; sub lastBusinessDayPrevQ { my( $y, $m, $d ) = unpack 'A4A2A2', shift; my $t = timelocal( 0,0,12, $d, $m-1, $y ); $t -= 43200 until localtime( $t ) !~ m[Mar|Jun|Sep|Dec]; $t -= 43200 until localtime( $t ) =~ m[Mar|Jun|Sep|Dec]; $t -= 43200 until localtime( $t ) =~ m[Mon|Tue|Wed|Thu|Fri]; ( $y, $m, $d ) = unpack 'x20a4 X20a3 xa2', scalar localtime( $t ); $m = { Mar=>'03', Jun=>'06', Sep=>'09', Dec=>'12' }->{ $m }; return join '', $y, $m, $d; } test(); sub test { ok ( lastBusinessDayPrevQ("20110901") eq "20110630"); ok ( lastBusinessDayPrevQ("20120101") eq "20111230"); }

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
