A shared calendar is a digital tool that allows multiple users to view and manage events and appointments in one place. It can be accessed through various devices, such as smartphones, tablets, and computers, making it convenient for collaboration. Users can add, edit, or delete events, ensuring everyone stays informed about important dates and activities. These calendars are often used in workplaces, schools, and families to coordinate schedules. Popular platforms for shared calendars include Google Calendar, Microsoft Outlook, and Apple Calendar. By using a shared calendar, groups can improve communication and organization, reducing the chances of scheduling conflicts.
