PHP Calendar Help

Some time ago I wrote a calendar, but the way I wrote it, the week went from Monday - Sunday, but I'd like to change that now to go from Sunday - Saturday.

I wish I could remember my logic behind the calendar, but it was just so long ago.

I know my <th> tag has Sunday first, but the code still displays as if it's monday-sunday, because the 24th comes up as a Wednesday which obviously is incorrect.

Thanks!

While it's hard to see everything that is going on with your code because some of the functions are being pulled in from the include files that aren't visible here, I have an idea on where to start..

In line 36 above, you are determining which day is the first day of the month by this code:  $FirstDayInMonth = date("N",$Timestamp);

the "N" that you are using in the php date function returns a numerical expression of the day of the week, with the number being between 1 and 7 (1 is Monday, and 7 is Sunday).  Since you want the week to start with Sunday, I would first change the code to read this:   $FirstDayInMonth = date("w",$Timestamp);    

changing the "N" to a "w" will change the possible range of numbers returned to 0-6.  In this case, 0 represents Sunday and 6 represents Saturday.  You can see the different parameters you can use with the date function on php.net  at  http://php.net/manual/en/function.date.php

Also, later in your code, beginning on line 72, you have a for loop where you start looping through the days of the week.  You will probably have to change the loop so that you loop from 0 to 6 (instead of 1 to 7).  Again, this is because date("w") in php returns a value between 0 and 6, with 0 being Sunday.
