Online calendars make it easy to manage and organize your schedule, appointments, events, and tasks. At their most basic, online calendar apps offer features like:

  • Creating, editing, and deleting events

  • Automating event reminders and notifications

  • Sharing calendars with others

  • Syncing across multiple devices

Many online calendars also offer meeting and appointment scheduling tools that sync with your personal and professional calendars. You can share your availability with others and find a time to meet in just a few clicks — no back-and-forth emails or calendar cross-referencing required.

In this guide, you’ll learn how to choose the right online calendar for your needs. We’ll also walk through seven of the top online calendars currently available — all of which offer free plans!

What to look for in an online calendar

As you consider different options, keep these questions in mind:

  1. Is it easy to use? The more intuitive the software, the sooner you’ll be able to get organized! Your online calendar should be easy to set up and navigate for you, your teammates, and anyone booking time with you, so everyone has a great experience. For example, automatic time zone detection makes it simple to collaborate across locations without having to do the mental math.

  2. Does it sync with other calendars? If you use Apple Calendar for your personal life, and an Outlook calendar at work, you run the risk of double-booking. Look for a tool that syncs with multiple calendars, so meetings don’t get scheduled over important events (or vacations!).

  3. How much control do I have over my schedule? Scheduling software should give you more control over your calendar, not less. Look for a tool that lets you set the number of meetings per day, which holidays are blocked off, how close together meetings can be, and how far in advance meetings must be scheduled.

  4. Can I schedule and manage different kinds of events? Some calendar apps only work for scheduling internal meetings, while others are focused on a single use case, like managing a family calendar or booking one-on-one appointments. If you need to schedule a variety of events with different combos of people, look for a calendar with flexible group scheduling, shared calendars, and multiple event types. 

  5. How customizable is it? Can you customize your calendar and event communications? Some calendar apps built for teams let admins set templates for calendar events and pre- and post-meeting communications.

  6. Can I use it across devices? Mobile apps and browser extensions make it extra simple to manage your schedule whenever and wherever you need. Look for a scheduling tool that works across desktop and mobile devices.

  7. What can I automate? Does the tool send automatic event confirmations, reminders, and other notifications via SMS and email? What about follow-up communications? Different apps offer different levels of automation, from simple reminders to more advanced workflows.

  8. Does it integrate with the other tools I use? You can have top-notch software, but if your tools don’t play well together, you’ll miss out on opportunities to keep info organized and get more done. For example, if you host meetings on Zoom, look for a calendar app that automatically adds Zoom meeting details to new events.
