A. 1. When creating a new event, make sure to uncheck the 'All-day' option if you do not want it to be an all-day event. 2. If you frequently create events that are not all-day, consider using a different time slot to avoid the all-day setting.

B. 1. Use the 'Event' settings to set a default time for new events. Open the app, go to 'Settings' > 'General' > 'Default duration' and set it to a specific time.
