Help with posting data to Calendar with dropdowns.

What i'm looking to accomplish is post events from one sheet to the calendar on the next sheet. Simple enough but instead of a big 12 month calendar for each entity, I'm looking to consolidate it into one Calendar view that anyone on my team can view their specific entity and responsibilities. Attached is a mock up of what i'm working with. Sheet 1 contains the calendar with a drop down for month and property, and sheet 2 contains the list of properties and the corresponding events/dates for the entity.

Thanks in advance, any questions or anything i can help with please let me know.
