As time seems to have melted into a giant globe in 2020, believe it or not, we still have some timetables to stick to – gasp. This is why having a digital calendar on your Mac with macOS Big Sur can save your life, as you can keep track of all your Zoom or Google Meetings, your telemedicine appointments, your virtual outings with your friends and family, etc. Maybe one day we can start having physical dates and meetings again, but either way, life gets hectic and keeping track of everything can be tedious. Here are some of the best calendar apps for Mac that we love.

Fantastical has been around for several years now, and although it has moved on to a subscription model, it remains the favorite calendar app for many of us here at iMore.

With Fantastical you get a fully functional desktop app that also has a menu bar version for quick access. You can customize your daily, weekly, monthly, and even yearly views, and your event planner also appears in the sidebar. If you’re running multiple calendars at once, things can get tricky – Fantastical lets you customize sets of calendars to display at once, and they can even be location-based, so things don’t get too crazy when viewing. For example, you can display work calendars while you are at work, but personal calendars when you are at home.

The natural language input is also top notch, as the app easily understands and fills in all the relevant fields while you type something as simple as “Lunch with Mom at In-N-Out Tuesday at 2 PM”

Although Fantastical now has a subscription model, previous Fantastical 2 users get most of the features unlocked, so it’s still very functional. If you are new to Fantastical, there is a trial run to test it out to see if you like it before deciding on a subscription. The free version has restricted functionality.

Fantastical has a nice easy to use interface and a lot of robust features.

Another great option is BusyCal. This app will automatically sync with any accounts you use with the Mail app on Mac, and everything will be up to date. The design of the app itself is simple and clean, but there are also a lot of powerful features. One of them is the smart filter, which allows you to create rules for the displayed events. For example, you can set a filter to show only birthdays or recurring events. BusyCal also lets you configure multiple smart filters at once, making it easy to organize your busy schedule.

Other BusyCal features include a menu bar app, travel time, natural language input, and a ton of customization options including font, size, colors, time format and much more. Moreover. If you don’t like Fantastical’s subscription model, BusyCal and its one-time cost is a great alternative to consider.



BusyCal contains a ton of useful features and is highly customizable. It also has a unique and unique cost.

Best calendar apps for Mac: Calendars

If you’re happy with the default Calendar app on Mac, but just want a companion app to go with it on the menu bar, then Calendars is worth checking out. This free app lives in your menu bar, acting as a viewer for the calendars you’ve set up in Calendar. It’s a quick way to see your schedule and agenda at a glance, so you can’t add new events from this app. There is an optional subscription that gives you more features, like adding Google Calendar accounts and backgrounds.

Need your calendar app to be more than just a calendar? Then Informant is the one you are looking for. This powerful app consolidates your calendar, task manager and notes into one, giving you everything you need at a glance. Informant’s task manager element is also very flexible, working with you, whether it’s GTD, Franklin Covey, or a simple, basic to-do list. Informant also supports multiple filters, so you can easily switch and access important items whenever you need them.



Informant combines your calendar, task manager, and notes app into one.

Best calendar apps for Mac: InstaCal – Calendar menu bar

If you want your calendar to live on your menu bar, but need a bit more functionality than calendars, then InstaCal is worth considering. This app also lives in your menu bar, so it’s not a full-featured app like the others. However, it keeps your calendar just a click away, so you can view your events, calendar and even tasks, while having the functionality to directly add new events and tasks. InstaCal works with any calendars you’ve already set up in Calendar, or you can manually add an unlimited number of accounts from Google, Office 365, and Outlook. It also supports dark mode, customization options, etc.

Do you want a simple and lightweight calendar app? The mini calendar does the trick perfectly. It gives you access to your calendars in three ways: on the desktop, from the Dock and from the menu bar. When it’s on the desktop, it’s always on and sits above the wallpaper. From the Dock, just click on the icon and the calendar will appear as a popup. The mini calendar is configurable in terms of color, hot keys and it can also show you sunrise and sunset times. It’s just a light and fast way to access your calendar when you need it.

The list is completed with Calendar 366 II, which is another menu bar calendar app. However, it is one of the most complete, which is quite impressive. With Calendar 366 II, you get full access to your calendar and reminders right from your menu bar, and you can change the view to year, month, week, day, calendar, or even list. It offers eight themes for light and dark modes, custom colors, calendar sets, custom font sizes, Spotlight integration, travel time, Alfred and LaunchBar support, and much more. . Bundling all the features of a full app into the menu bar is pretty amazing, and the cost of the app isn’t too high either, all things considered.
