Django - If you have 2 date-pickers in the admin form, one for start date and one for end date, this will make sure the second picker is the same month as the first. Which improves the usability of the picker.

change_form.html

{% extends "admin/change_form.html" %}
{% block extrahead %}
{{ block.super }}
<script >
// override openCalendar to set the date of calendar A to calendar B
var _openCalendar = DateTimeShortcuts.openCalendar;
DateTimeShortcuts.openCalendar = function(num) {
	_openCalendar.call( this, num );
	var cals = DateTimeShortcuts.calendars;
	cals[1].drawDate( cals[0].currentMonth, cals[0].currentYear );
};
</script>
{% endblock %}
