Calendar is a personal organiser program that was distributed with Microsoft Windows from version 1.01 until Windows 3.11. It was superseded by the calendar in Microsoft Schedule+, which was included in Windows for Workgroups and Windows NT. Windows 95, Windows 2000 and their descendants did not include a calendar program until Windows Vista, but Windows XP can run Microsoft Calendar. Note: Some Windows Longhorn betas have a clock app on the sidebar, that when opened, a calendar applet will open.

Saved Calendar files have the extension .cal. The Calendar file format was one of those described in Volume 4 of Microsoft's Windows 3.1 Programmer's Reference. ^[1]

Two 32-bit versions of Microsoft Calendar were found in the Windows NT/2000 source trees: one was a simple port of Calendar from 16 to 32-bit, and the other was a Unicode-compatible version. However, the applet did not make the final cut, along with implementations of Microsoft Cardfile, Clock, Cruel Solitaire, Golf Solitaire, Pegged (peg solitaire), Reversi, Snake, and Tic-Tac-Toe.^{[citation needed]}
