In the dictionary, "event" is defined as an occurrence happening at a determinable time  and place, with or without the participation of human agents. Here is a depiction of an event as it relates to time.

In the platform, all events and sessions (sub-events happening within an event) should have:
1. Start date & time
2. End date & time

In relation to a present moment of time, events can be past, present, or set up for the future.
To be consistent and establish a uniform terminology, we will call these events and/or sessions:
1. Active (present) 
2. Past 
3. Future

From the platform user perspective, the importance of the events can be classified as follows:

Event Type Urgency Description
Active Event High Event is happening now and is at its peak importance. 
Future Event Medium Event occurs in the future, but details are imperative for planning.
Past Event Low Event has occurred. Organize and analyze results.

In this light every event or session can have one of three statuses on the platform:

Event Type Event Status Indicator color
Active Event Active Green
Future Event Upcoming Yellow
Past Event Ended Red
