A digital calendar would be the best option for Darius because it allows him to easily see his schedule at a glance, receive reminders for upcoming meetings, and have all meeting details (such as date, time, location, and attendees) in one centralized location. This can help him stay organized, avoid double booking, and easily reference past or upcoming meetings. Additionally, a digital calendar can easily sync with his email and other devices, making it convenient for him to access and update his schedule on-the-go.
