for each of the scripts posted you should have an active link to a site which is using that script!

just a thought

sorry, but this script runs only on a lan-server and is not accessable through the internet.

I was able to integrate this clever little calendar with MySQL with these modifications . . .

Code posted here was beginning some months with the date "2", at least on my host`s Linux/Apache/PHP4 server. Was able  to change Brandl`s get_mARRAY() function to get the arrays always to start with "1" (with the first day in the weekrow being Sunday rather than Monday, as is common) by changing the function get_mARRAY() as follows:

function get_mARRAY() { 
    global $intDATE; 
    global $d; 
    global $m; 
    global $j; 
    if (date("w",mktime(0,0,0,$m,1,$j))==1) { 
       $startDAY=mktime(0,0,0,$m,1,$j); 
    } elseif (date("w",mktime(0,0,0,$m,1,$j))==2) { 
       $startDAY=mktime(0,0,0,$m,0,$j);
    } elseif (date("w",mktime(0,0,0,$m,1,$j))==3) { 
       $startDAY=mktime(0,0,0,$m,-1,$j);
    } elseif (date("w",mktime(0,0,0,$m,1,$j))==4) { 
       $startDAY=mktime(0,0,0,$m,-2,$j);
    } elseif (date("w",mktime(0,0,0,$m,1,$j))==5) { 
       $startDAY=mktime(0,0,0,$m,-3,$j);
    } elseif (date("w",mktime(0,0,0,$m,1,$j))==6) { 
       $startDAY=mktime(0,0,0,$m,-4,$j);
    } else { 
       $startDAY=mktime(0,0,0,$m,-5,$j);
    } 
    for ($i=1;$i&lt;=42;$i++) { 
    $marray[$i]=mktime(0,0,0,date("n",$startDAY),date("j",$startDAY)-2+$i,date 
("Y",$startDAY)); 
    } 
return $marray; 
} 

Spelling out the value for each day is a lot clunkier than Brandl`s code but it worked for me.:) But what finally made it all work was inserting that "-2" in ""j",$startDAY)-2+$i" in the for loop.

You can also change "target=_blank" to "target=_self" in the html anchor if you don`t want to open a new window.

The way this little calendar creates numerical year, month and day values (e.g., href=calnav.php?j=2001&m=5&d=1) makes it very easy to assemble a date variable and launch a MySQL query.

Thanks, Brandl.

the problem here is:
here in europe, we start each week with monday. some systems report the sunday as weekday 1 (i think, thats`s the american system) of the week. i`m not sure if it`s the php function date() that is responsible for this. if your system reports the monday as day 1 of a week, just change the folloeing line from:
     if (date("w",mktime(0,0,0,$m,1,$j))==2) { //if 1st of reque....
to
    if (date("w",mktime(0,0,0,$m,1,$j))==1) { //if 1st of reque....

i hope, this helps.
