Calendar Start Day

[keframil]

Thank you for the reply, but I figured it out.
Took me a couple of days going trough every file in the code but managed to find what to edit.

Could you please supply your solution here in this topic? I am sure it is helpful for others.

I meant to do that. Here you go:
Go to: plugins\calendar\inc
Open calendar.php

First 3 lines of code:

function c_firstDay($month, $year) {
    $day = date('N', mktime(0,0,0,$month,2,$year));
    return $day;

make sure to change to a number 2 just before ,$year)); on the second line and save it.

Then Open:   client_calendar.php
scroll down to the table for the days of the week and move this line to the beginning of the table(just before Monday)

<th class="sunday"><?php i18n('calendar/Sunday'); ?></th>

And that's it.
Enjoy
