One Calendar

One Calendar is a lightweight visual calendar app for Windows 10 and Windows 11 PCs, enabling users of all knowledge levels to unify all their digital calendars into a single application where they can take advantage of the clear overview of all imported data points, enjoy an eye-catching visual design, quickly switch between available display modes (daily, weekly, monthly and yearly views), personalize the look of the app, and accelerate daily workflow with fast and reliable calendar overview tools optimized for both desktop and touchscreen use.

Originally created in 2014 by the development team at Code Spark, One Calendar has managed to dramatically expand its functionality and become one of the most downloaded calendar applications on the Microsoft Store. Today, One Calendar has built-in support for live synchronization with an incredible variety of cloud-powered calendar services, including Windows Live, Hotmail, Google Calendar, Facebook, iCloud, Office 365, Outlook.com, and Exchange, making it a perfect choice for users who want to unify all those calendar services into one highly streamlined platform where all their scheduled events will be clearly marked and easy to notice.

The app features a wide array of added features in addition to simple event listings. It can be accessed when the user’s PC is fully offline and without an active internet connection, and even supports a drag & drop interface that can speed up daily productivity when managing a large number of calendar entries. A streamlined user interface with built-in theme support can enable users to set up their calendar overview in colors that best fit their needs, which is especially useful for users with vision issues.

The powerful search tool enables users to quickly identify any type of event – from birthdays, scheduler work tasks, and even Facebook Events. All data handled by One Calendar is kept secure and inaccessible by unauthorized users with comprehensive local encryption.
