Calendar events slow load

A potential bug can appear while going back at least two months with the today link. By being at least two months away from the "today month" the events for the "today month" have not been loaded yet. Sometimes loading these can take time and while it's loading you can still send json requests by clicking an event day (This is all before the day gets the class event and has a dot on it). By doing this you can make more than one ticket of the same event in the day-content container, as you can see below. Not the most urgent bug, but an annyoing one.
