A schedule or a timetable, as a basic time-management tool, consists of a list of times at which possible tasks, events, or actions are intended to take place, or of a sequence of events in the chronological order in which such things are intended to take place. The process of creating a schedule - deciding how to order these tasks and how to commit resources between the variety of possible tasks - is called scheduling, and a person responsible for making a particular schedule may be called a scheduler. Making and following schedules is an ancient human activity.

Microsoft Schedule+ is a discontinued time management app developed by Microsoft. After discontinuation, most of its functionality was incorporated into Outlook 97. It was originally intended as a companion to Microsoft Mail, but was later shipped with Exchange Server 5.0, Microsoft Office 95, Exchange Client and Windows Messaging. The "Outlook Calendar" that was part of Outlook for Windows 3.1 and Macintosh versions before 9.0 was actually a new version of Schedule+. After discontinuation, it was with all versions of Microsoft Office up to Microsoft Office 2003, although it is just to support conversion from Schedule+ 1.x.
