Have a look at Date#commercial ( 
http://www.ruby-doc.org/stdlib/libdoc/date/rdoc/classes/Date.html#M000158 
)

  require 'date'

  def week_dates( week_num )
    year = Time.now.year
    week_start = Date.commercial( year, week_num, 1 )
    week_end = Date.commercial( year, week_num, 7 )
    week_start.strftime( "%m/%d/%y" ) + ' - ' + week_end.strftime( 
"%m/%d/%y" )
  end

  puts week_dates(22)

hth,

Siep
