Atomcal core is an infinite scrolling canvas of weekdays that can be expanding into a timeline view. As a user, you can use arrow keys to go back and forth between the days. Once expanded you can also create an event by dragging on the timeline between a certain time.
The event can then be expanded by clicking on it to add more details like the event name and description etc. Once an event is created, the timeline can then be collapsed to only see the scheduled event in a day's agenda view.
If two or more events are at the same time, these events will stack on top of each other in a unique way when in agenda view. To delete an event just drag the event from the timeline view out of the window (in the trash bin that pops up in the header to be precise).
