How do you define a business day? Is it weekdays? Or do you need to take into account public holidays and things like that?

Here's a naive approach that just leaves you needing to define an is_business_day() subroutine which takes a time (as an epoch seconds value) as an argument.

my $today = time; my $days_added; while (1) { $time += 24 * 60 * 60; # add a day $days_added++ if is_business_day($time); last if $days_added == 10; } print scalar localtime $time;

Update: As ikegami correctly points out below, there's a potential bug in this program if it's run across days that don't contain 24 hours (i.e. when switching to or from daylight saving time). The fix is to normalise the time to noon (assuming that timezone changes always occur overnight). This change is left as an exercise for the reader.

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.
