Does anyone know if there is an event calendar module which would allow refining by day as well as by state? Thank you in advance!

You may need to explain further what you mean by "state". Is this a value like NY,GA,CA? or something like unpublished vs published?

Both Calendar and FullCalendar modules allow you to create calendars using Views. With Views you can filter by fields or allow the user to filter with exposed filters.

Also, are you really using Drupal 8.x? it is not released yet.
