It is a transient notification, typically displayed on the screen, designed to inform the user of an upcoming or ongoing event.

They allow users to stay informed about their schedules and commitments without needing to actively check the calendar application. Historically, their functionality has evolved to include features like snooze options, quick actions to join meetings, and custom alert sounds, enhancing user productivity.
