My application needs to show some notifications for schedules (like Alarm), based on time interval.

For example:

There are 4 tasks I have setted in my application, like

Task A -> from 10:00 to 13:00
Task B -> from 15:10 to 16:00
Task C -> from 17:00 to 17:30
Task D -> from 20:00 to 23:30

So notification should be shown as

at 10:00 Task A has started

at 13:00 Task A has ended

at 15:10 Task B has started

… and so on.

How can I implement this? Can you please provide some tutorials related to it?
And if there are more than one way, which is the best way to do this?
