There are a few different ways to delete events from your Alexa calendar. You can say "Alexa, delete my event for today," which will remove any event that is scheduled for the current day. Alternatively, you can ask Alexa to "delete my event for tomorrow," which will remove any event that is scheduled for the following day. Finally, you can say "Alexa, delete all of my events," which will remove all events from your calendar. If you need help deleting an event, you can always ask Alexa for assistance.
