Navigating The Calendar App Landscape on Windows

Dec 1, 2023

There's no denying that a well-organized calendar is the cornerstone of a productive schedule. It's your lifeline in the sea of tasks, appointments, and reminders that flood your daily life. However, with countless tabs open on your browser, it can be easy to lose track of your calendar amidst the clutter. This is where dedicated desktop calendar apps come to the rescue, especially for Windows users.

Why Choose a Desktop Calendar App?

In this digital age, anyone can easily access Google Calendar from their browser. But if you're looking for something more, a desktop calendar app is what you need. Desktop calendar apps are designed to cater to your unique needs and provide a more customized experience. They offer a native Windows interface, a schedule overview at a glance, easy appointment addition, timely notifications, and sync options with multiple platforms.

Selection Criteria for the Best Windows Calendar Apps

When it comes to selecting the best calendar app for Windows, several factors come into play.

  1. Native Windows Interface - The calendar app should feel like it belongs in Windows, offering native features like keyboard shortcuts.

  2. Schedule Overview - The app should show your schedule at a glance, whether you prefer a week view or an agenda of the day's appointments.

  3. Easy Appointment Addition - Adding appointments should be quick and simple, ideally possible using only keyboard shortcuts.

  4. Timely Notifications - The app should provide optional notifications when an event is about to start.

  5. Sync with Multiple Platforms - The calendar should sync with your phone at the very least. Ideally, it should also sync with Google, Apple, and Microsoft accounts, along with advanced options for CalDAV and iCal.

Best Windows Calendar Apps

After conducting a thorough evaluation and rigorous testing of twelve different Windows calendar applications, we have identified and selected the top four options that truly excel in terms of their impressive functionality and remarkably user-friendly interface.

Windows Calendar

Built into Windows, this calendar app is a user-friendly and efficient tool that offers a range of convenient features. With seamless integration, it supports various popular calendar platforms such as, Office 365, Google, Yahoo, and iCloud. This ensures that you can effortlessly synchronize your events and appointments across devices. In addition to its basic functionality, this app stands out with its unique offerings. It allows you to easily add sports, TV, and international holiday calendars, catering to diverse interests. Moreover, it provides the option to display upcoming appointments directly on the Windows lock screen, ensuring that you never miss an important event.

Microsoft Outlook

Microsoft Outlook is a versatile and comprehensive application that offers much more than just email functionality. With its integrated features, it seamlessly combines email, calendar, contact management, and task list into a single user-friendly interface. This all-in-one solution is particularly beneficial for individuals who are loyal Microsoft users, as it allows them to effortlessly merge their email communication with their scheduling needs. While it may not have the capability to sync with Google Calendar, Microsoft Outlook remains an ideal choice for those seeking a unified and efficient digital workspace.


OneCalendar is a versatile calendar app that offers synchronization with a wide range of platforms.

Mozilla Thunderbird

Primarily known for its email client capabilities, Mozilla Thunderbird also boasts a robust built-in calendar feature. While it may not have the convenience of adding Google Calendar or other services by default, this limitation can easily be overcome by utilizing add-ons. One of the key advantages of Thunderbird is its open-source nature, which grants users unparalleled flexibility. With a vast array of extensions at your disposal, Thunderbird stands out from other applications in terms of customization options.

Alternatives for a Windows Calendar

If none of these options appeal to you, consider the following alternatives:

  • Rainlendar: Adds calendar widgets to your desktop and can sync with other services for a fee.

  • TickTick: A to-do list app with a built-in calendar.

  • Google Calendar: Can be used in your browser of choice, but it won't provide a native desktop experience.

  • Paper-Based Productivity System: If all else fails, you can always switch to a traditional paper-based system.


In conclusion, when it comes to determining the best calendar app for Windows, the answer is subjective and highly dependent on individual needs and preferences.
