The output is:
$monthDescription.= ' from ('.sdate($fromdate). ' till '.sdate($todate).')';
In the script supplied, the format or calculation is not shown for $fromdate.
If and only if $fromdate is in a “timestamp” format then formatting options are avaialable here:
**Example: **
$fromdate = time();
echo date('l, F jS, Y H:i:s', $fromdate);
// output: **Sunday, December 13th, 2015 02:53:32**
