Calendar is a personal calendar application made by Microsoft. It offers synchronization of calendars using Microsoft Exchange Server, Outlook.com Apple's iCloud calendar service, and Google Calendar. It supports the popular iCalendar format.
Microsoft first included a Calendar app in Windows 1.0, which was included until Windows 3.1, and was replaced by Schedule+ in Windows for Workgroups and Windows NT 3.1. Schedule+ was later moved from Windows to the Microsoft Office suite, and Windows did not include another Calendar application until Windows Calendar in Windows Vista. Calendar had been created by Beta 2 of Windows Vista.
This version supports sharing, subscribing, and publishing of calendars on WebDAV-enabled web servers and network shares. It has always supported .ics files, and the subscription feature enables syncing with Google Calendar. Its interface matches Windows Vista Mail's, but the two apps are not connected in this operating system. The default calendar can be renamed.
A new version of Calendar with a text-heavy was added to Windows 8 as one of many apps written to run full-screen or snapped as part of Microsoft's Metro design language philosophy. It is one of three apps on Windows that originate from Microsoft Outlook, the other two being Mail and People apps. Structurally, the three apps are one and are installed and uninstalled as such. But each has its own user interface. Calendar in Windows 8 originally supported Outlook.com, Exchange, Google Calendar, and Facebook calendars. Because of API changes, Facebook and Google calendars can no longer be directly synced on Windows 8. Like many Microsoft apps introduced for Windows 8, many of the features are hidden in the charms or a menu at the bottom of the screen that is triggered by right clicking. Different calendars can be labeled with different colors. When a user with a Microsoft account adds a calendar account on one computer with Windows 8 Calendar, the account will be automatically added to all other Windows 8 computers the user is logged into. .ics files are not supported in this version.
Mail has preset server configurations for Outlook.com, Exchange, Google Calendar, and iCloud Calendar. Users can set it to use the system theme or choose a custom accent color, background image, and light/dark preference. Windows 10 Calendar has multi-window support for viewing and editing events. Different calendars can be labeled with different colors, and events can be rearranged by dragging and dropping. The default interface is Month View, but users can also use Day, Week, and Year views and print these views. The Windows 10 app also uses a flyout settings panel and a mini Ribbon interface in the viewing pane. The day of the year and calendar events show on the live tile. Like the Vista version, the important controls are readily visible and use icons to match the system's. Accounts can be grouped and relabeled, but folders cannot be edited from within the app. .ics support was added to this version in time for the Windows 10 Anniversary Update.
