Projects Page
You can create a category called Events and add all your Events there as Projects.
While you are on the Projects Page, you can also consider tags to identify your events among the other projects.
Task Page
You can create a category Events under the General tasks as these events don’t belong to a project, and add them there.
And if the event is a task in a project, you can use tags to identity it.
Time page
Use filters to identify events on a calendar and timeline.
Reports
Reports can be generated using filters to identify Events.
