extracting columns falling within specific ranges for multiple files

Hi, I need to create weekly files from daily records stored in individual monthly filenames from 1999-2010. my sample file structure is like the ones below:
Code:
daily record stored per month: 
199901.xyz, 199902.xyz, 199903.xyz, 199904.xyz ...199912.xyz

records inside 199901.xyz (original data has no header)
lat lon wind year month day
12.5 121.0 3.4 1999 1 1
12.4 121.1 2.2 1999 1 1
12.1 122.1 1.2 1999 1 2
12.3 124.3 1.0 1999 1 3 
12.5 122.2 1.8 1999 1 3...
12.1 123.7 2.3 1999 1 31

I want to output the values of lat,lon,wind based on a 7-day range and end up with this below:
Code:
199901_wk01.txt contains the values of lat,lon,wind for days from 1-7
199901_wk02.txt contains the values of lat,lon,wind for days 8-14
199901_wk03.txt contains the values of lat,lon,wind for days 15-21
199901_wk04.txt contains the values of lat,lon,wind for days 22-28

199902_wk01.txt contains the values of lat,lon,wind for days from 1-7
199902_wk02.txt contains the values of lat,lon,wind for days from 8-14
199902_wk03.txt contains the values of lat,lon,wind for days from 15-21
199902_wk04.txt contains the values of lat,lon,wind for days from 22-28

and so on for the rest of the files.

Thanks much in advance.

NAME
iCal::Parser::HTML - Generate HTML calendars from iCalendars SYNOPSIS
use iCal::Parser::HTML; my $parser=iCal::Parser::HTML->new; print $parser->parse(type=>$type,start=>$date,files=>[@icals]); DESCRIPTION
This module uses iCal::Parser::SAX and XML::LibXSLT with included stylesheets to generates html calendars from icalendars. The html document generated includes (when appropriate) a sidebar containing a legend, a list of todos and a three month calendar for the previous, current and next months. The stylesheets are stored in the HTML/stylesheet directory under the installed package directory. Also included in this package are an optionally installed command line program "ical2html" in scripts and, in the example directory, a cgi handler ("ical.cgi" in examples) and a stylesheet ("calendar.css" in examples) for formatting the html output. Note that the html output will look quite broken without the stylesheet. ARGUMENTS
The following arguments are processed by this module. Any addtional arguments are passed to iCal::Parser::SAX. type The type of calendar to generate. One of: "day", "week", "month" or "year". The daily, weekly and monthly calendars include the sidebar. The calendar generated will be for the specified period (day, week, etc.) which includes the specified date. start The date to generated the calendar for. The date only needs to be specified to the precision necessary for the type of calendar. That is, "YYYY" for a yearly calendar, "YYYYMM" for a monthly, and "YYYYMMDD" for daily and weekly. In addition, the date can be in one of the following forms: YYYY[MM[DD]] YYYY[-MM[-DD]] A DateTime object initialized to the necessary precision files An array reference to the list of icalendars to include in the results. url If this params is specified, then the html output will contain links back to this url for getting other calendar periods. The params "type" and "date" will be appended to this url when generating the links. AUTHOR
