9 Google Calendar Extensions to Boost Productivity

Looking for a boost in productivity? Consider one of these 9 Google Calendar extensions to elevate your schedule for more effective planning.

If it’s not on Google Calendar, does it really exist?

For meetings, reminders, time blocks, and more, Google Calendar is where you’ll find a ton of information regarding what awaits during the day, week, or month ahead. And while it’s an incredibly useful tool, it may not be perfect or have the most necessary features for everyone all the time.

Thankfully, there’s likely an extension that has everything you’re looking for—and so much more.

What are the benefits of Google Calendar extensions?

There’s no denying just how popular Google Calendar is. In fact, it’s used by over 500 million people and is available in 41 different languages. It’s often one of the first websites people fire up at the start of the workday to see what meetings await and what items are on their to-do list.

The right Google Calendar extension can allow users to add customizations and small tweaks that the app itself is missing. Maybe you need different types of reminders, a better way to visualize events, or better note-taking abilities—an extension added to an already great app like Google Calendar can give you the personalized features you may need. 

Whatever the case may be, a Google Calendar extension is the one thing your calendar is missing and what will take productivity to the next level.
