When an event registration shows up on the admissions calendar it is showing a combination of information from both the event registration itself, as well as the specific registration items in the event. The item on the admissions calendar will show as the Event Registration Name - Registration Item Group - Registration Item, so as an example, and event by the name of Open House with a registration item group of Open House Dates, and a Registration Item of Jan 01 will show as Open House - Open House Dates - Jan 01. The date that the registration item will show on the admissions Calendar is also controlled by the date set for the Registration item, rather than the date set for the Event Registration
