How to start calendar on a specific date

Applications Calendar
#1

Hi there,

this script used to work but after the last update it does nothing…
any suggestions to get this working?

$datum=‘2015-12-31’;

echo ‘<script>
window.onload = () => {
setTimeout(() => {
$("#calendar").fullCalendar(“gotoDate”, "’.$datum.’");
}, 10)
}
</script>’;
