How should a sales rep create an all-day event in Salesforce?

To create an all-day event in Salesforce, the sales rep should check the all-day event checkbox. This specific action signals to the system that the event spans an entire day rather than being scheduled for specific start and end times. When this checkbox is selected, Salesforce adjusts the way the event is displayed, showcasing it as occupying the entire day on calendars, which is essential for events such as conferences or holidays that do not occur at specific times.

The other methods mentioned do not directly lead to creating an all-day event. Consulting the System Administrator may provide additional guidance but does not influence the process of creating the event itself. Scheduling the event within standard work hours contradicts the nature of an all-day event, as the latter requires it to extend beyond set time frames. Lastly, using a task instead of an event is not appropriate since tasks are typically for to-do lists and do not represent larger, time-bound events that require visibility on shared calendars.
