A program or piece of software that facilitates the planning and arranging of meetings for two or more persons is called a meeting scheduler. Usually, it lets users enter meeting information such the date, time, place, and number of participants before inviting everyone to the meeting. To make sure the meeting doesn't interfere with other planned activities, the scheduler may also monitor replies to invitations, notify participants of meeting information, and even link with calendars. Teams or busy professionals that regularly need to organize meetings with customers, clients, or colleagues may find this tool very helpful.
