To use this plugin with custom date format on date_add and date_sub here is how to easily fix it. Go to the Plugins -> Plugin Editor then select Date Calculator. You are now on editable date-calculator.php FOR date_add There you need to find line 203 and replace with this code: $datecalc = date($format, mktime(0, 0, 0, date("m")+$month, date("d")+$day, date("Y")+$year)); FOR date_sub Find line 244 and replace with this code: $datecalc = date($format, mktime(0, 0, 0, date("m")-$month, date("d")-$day, date("Y")-$year)); Now you can use custom date format.

the only one reason I dl this plugin is automatic display for a future date based on today, but too bad there's a format issue for date_add short code, please fix this in the next update, thank you, good job.
