Under this section, teachers are facilitated with flexibility to manage school event schedules based on their availability and preferences. Additionally, it allows them to make modifications and adjustments whenever they are needed. The Teachers, Vice Principal, and Principal can Add, Update, and Delete Events from this function. When users navigate to the Calendar page, they can see the scheduled digitalized calendar. In each event, it is mentioned event detail summary with an allocated date and time. If a user wants to add an event to the calendar, they can click the Add button and schedule the event based on their preferred date and time. If the date is already booked, it mentions the user and then suggests an alternative time slot. If there is no overlapping event for the chosen time slot, the system previews event details form to the user for final adjustment. Then the user can submit and wait for the approval.
Then the event details form is submitted, it is sent to the vice principal for review. The vice principal can check the form, verify the details and then provide approval for the event. If it is approved, it notifies the user who added the event and updates the digital calendar. As it is, the user can update and delete the event within three days of the scheduled time. Additionally, notifications are sent to keep users informed about any schedule updates or changes.

This function's special feature is Smart-Scheduling. If users enter the event details into the system, then select Smart-scheduling features. It recommends the best date and time based on past data, attendance tracking, and external variables like weather. For instance, while planning a sporting event, the AI can use historical data and current weather information to suggest the ideal timing, preventing conflicts and guaranteeing ideal weather for outdoor activities. This will improve planning accuracy.
