Calendar v 2.5.1
By: Stan Lemon ([url]www.stanlemon.net[/url])
Original by: Jim Wright
2003.06.30

As I continue to develop my dream "Calendar" class I have made several modifications
to my original alteration of Jim Wright's.

A big part of this version was the removal of several functions, and the removal of
the jdmonthname() and juliantojd() because not everyone has	Calendar support enabled. The
functions which I removed are: getWeekOfMonth() isLeapYear() and calendarInterface() because
they were no longer used by the calendar generator.

As I continue to learn more about object oriented programming I will also continue to
clean up this code.  I am also working to make it more customizable, and in turn, provide
for a more flexible, and more usable calendar class.

There is also error checking, to make sure that we get valid information.

Here is a simple list of things I have left to do:
	- Customize total look of calendar (This will be a 3.0 change)
	- Query string preserver (This is REALLY important!)
	- Make the rest of these functions more usable outside of generating a calendar.
	- Marking of current date.
	- Possibly implement some JavaScript to allow for "reminders"

i know you're going to have to switch these two table cells:

        <td bgcolor="' . $dayBgcolor . '" width="27" align="center"valign="middle" style="color: ' . $dayColor . '"> 
            Søn 
        </td> 
        <td bgcolor="' . $dayBgcolor . '" width="27" align="center"valign="middle" style="color: ' . $dayColor . '"> 
            Man 
        </td>

and i'm not entirely sure, but i think if you modify this function:

    function getDayOfWeek($dd, $mm, $yy){ 
        //returns int giving day of week for a date 
        $dateArray = getdate(mktime(0,0,0,$mm,$dd,$yy)); 

    return $dateArray['wday']; 
}

then that might be all you need. $dateArray['wday'] contains the integer corresponding to the day of the week...it starts on sunday...so you might try this:
WARNING: the php documentation says that strftime using %u will return integer day of week with monday as 1 and sunday as 7 but this appears to be different on different platforms.

    function getDayOfWeek($dd, $mm, $yy){ 
        //returns int giving day of week for a date 
	$day_int strftime("%u", mktime(0,0,0,$mm,$dd,$yy));
	return $day_int-1;
    }

another approach might be this:

    function getDayOfWeek($dd, $mm, $yy){ 
        //returns int giving day of week for a date 
        $time_stamp = mktime(0,0,0,$mm,$dd,$yy); 

return (date('w', $time_stamp) + 6) % 7;
}

...i'm not sure this will work, but it's a start...the crux of your problem is that the calendar loops thru the days with this code:

            for ($c=0; $c<=7; $c++){

that is what loops through the days of the week. but the code is formatted so badly that i can't figure out which parts are inside that for loop and which are not. you might want to try cleaning up your code--it would make things easier.

Thanx... It did the trick...

The only thing I had to do, was rearrange the days, and use this function

function getDayOfWeek($dd, $mm, $yy){  

        //returns int giving day of week for a date 
        $time_stamp = mktime(0,0,0,$mm,$dd,$yy);  

return (date('w', $time_stamp) + 6) % 7; 
}
