Try looking in the calendar.pl file for the text "
# Get selected date". The next line is:
$selected_datestring = $in{'selected_datestring'} ||
$year.&LZ($now_mm).&LZ($now_dd);
Try changing it to:
$selected_datestring = $in{'selected_datestring'} ||
$now_yy.&LZ($now_mm).&LZ($now_dd);

This is untested so use at your own risk. I don't know what other affects it might have, possibly none at all.
Please let the forum know if it works.
