Question:

How do I schedule a multi-day calendar event that shows on all of the days of the event?

Use the recurring event options on the calendar.

Add a new recurring event. Then on the new recurring event form, in the "Event Spans" option, select the number of days in a row the event will last. Leave the "Repeat Every" and "Stop After" options at their default settings unless you want this multi-day event to repeat every month, or year, or any other combination. Then enter the details and save the event.

This will create a calendar entry for each day of the multi-day event.
