Google Calendar Statistics in 2025: Judging the Book by Its Cover
You can get a pretty good idea of how Google Calendar is operating by reviewing statistical data.
These numbers don’t lie, and they show exactly where the service’s parent company, Alphabet, plans to take it moving forward.
The beta release of Google Calendar was back in 2006, and it has evolved immensely since then.
In today’s world, it’s known as an application more than anything and is capable of much more than remembering birthdays or a doctor’s appointment.
The following statistics offer a glance at Google Calendar’s current situation in its particular market.
1. Half a Billion Monthly Users
There was a time when you’d come across plenty of people who didn’t use any kind of Google product.
This isn’t the case anymore, considering how far Google has come.
Taking a look at the apps’ user base, you’ll find there are over 500 million monthly active users.
With everything being underneath the Alphabet name, Google consists of many things, but its calendar application still stands tall.
Even if smartphones and other applications offer various calendar services, many people default to Google Calendar.
You also want to take into account that it can be integrated with a broad variety of Google products.
Many users appreciate the synchronization between their Gmail accounts and Google Calendar.
It’s a reliable tool that seems to only get better with time, and its user base could very well surpass 1 billion people down the line.

While some people are going to lead busier lives than others, Google Calendar takes the stress off managing short and long-term commitments.

3. A Highly Rated Calendar App
You can sit there and compare ratings all day, but the reality is that Google Calendar sits pretty high on the list.
On the Play Store, the Google Calendar app has accumulated over 3 million reviews.
Even with all of the varying sentiments between individual users, it boasts an average rating of 4.4 out of 5 stars.
Once again, it’s important to remember that this can easily swing one way or the other.
Considering the service has been on the market since 2006, it’s safe to assume Google knows what they’re doing with it.
Google Calendar has evolved a lot over the years, and the fact that it has adhered to user needs time and time again is a testament to why the app has such a positive rating.
When it comes to app ratings, users consider much more than just the features themselves.
Thankfully, Google Calendar hasn’t wavered yet, and users seem to be happy about it.

4. Monthly Mobile App Revenue
This figure isn’t all-encompassing, meaning Google Calendars’ total revenue includes several sources.
For this section, we’re solely focusing on revenue that stems from the Google Calendar mobile application.
It’s also important to note that this data comes from 2021 but is still seen as the most consistent information.
During that time, Google Calendar was averaging $194,000 per month from the mobile application alone.
Google doesn’t charge a subscription fee for access to calendar features, but there are revenue streams that stem from companies, schools, and many other organizations.
For example, additional calendar features are available for those who sign up for a Google Workspace account.

5. The Number of Mobile App Users
Part of what sets Google Calendar apart from the competition is its mobile application.
Users love an app that suits their needs.
Google Calendar had roughly 4.4 million mobile app users back in September of 2021.
You can assume that this number is relatively high for this particular category nowadays.
The statistic highlights how quickly the application has grown in such a short amount of time.
It can be helpful to also remember that applications like this benefit from the lockdowns during the pandemic.
More than ever, people rely on technology to stay on top of their personal and professional responsibilities.
Overall, Google Calendar has proven itself to its users throughout the years, and many of its mobile app users will likely never use another calendar.

Within its particular market, there’s plenty of competition to keep Google Calendar on its toes.

6. Websites That Use Google Calendar
Combining both live and historical websites, there are roughly 1,161,671 websites that have or currently utilize Google Calendar.
This is made possible through the many integrations Google Calendar is known for.
Not only do people use it for personal reasons, but many use it to schedule meetings with clients and much more.
You can break down that large number into a few subcategories as well.
For example, there are 805,254 live sites using Google Calendar, and there are 356,417 historical domains that previously used the service.
Moreover, here are the percentages of the top websites in the world, based on traffic volume, that make use of Google Calendar:
- Top 10k = 2.39% (239)
- Top 100k = 1.9% (1,897)
- Top 1 million = 0.68% (6,835)
These numbers may seem small, but it’s a decent penetration rate within a fairly oversaturated market.
Make no mistake: there’s no shortage of calendar applications for both Android and iOS devices.

7. Break it Down By Country
The statistics mentioned above provide a bird’s-eye view of the matter, but it’s also interesting to see how that data is broken down by country.
Giving it a quick look, it’s immediately clear that Google Calendar is most popular in the United States.
At this time, there are roughly 540 771 websites in the U.S. that are using Google Calendar.
The country that’s next in line doesn’t even come close, which is the U.K. at 21,505 websites.
Here’s a better look at the number of websites in various countries that are currently using Google Calendar:
| Country | # of Websites Using Google Calendar |
| United States | 540,711 |
| United Kingdom | 21,505 |
| Brazil | 17,879 |
| Japan | 14,967 |
| Canada | 14,656 |
| Germany | 12,935 |
| India | 12,785 |
The numbers start to dwindle quite a bit after the U.S.
It’s safe to bet that this is likely due to the early adoption rate in the U.S. since that’s Google’s headquarters.
Nevertheless, we’re looking at years after its launch, and the rest of the world is slowly but surely adopting the service as well.
It’s surprising how low some of these numbers are, considering how long Google Calendar has been on the market.
Regardless of how popular the service may be, other regions in the world may prefer native service of their own.

While many similar services fall behind in the Collaborative Calendars category, there’s one technology that contends with Google Calendar: Wix.
While the Wix company is primarily known for its role in website building, it’s highly regarded for its calendar features as well.
The two services may be quite different, but Wix has a market share of 56.44%, while Google Calendar has 23.91%.
For a full scope of Google Calenar’s competition, review the details in the chart below.
While there’s no doubting the popularity of Google Calendar, it’s clear that many people default to Wix.
You also want to consider the number of users that merely utilize Google Calendar because they manage a website.
There’s a long list of reasons as to what leads someone to use Google Calendar over other services.
However, it may be a while before it even gets close to Wix’s market share.
This isn’t necessarily a bad thing, as Google Calendar and Wix are quite different.
Their target markets aren’t exactly the same, so some might even call this indirect competition.
Nevertheless, Google Calendar has to keep innovating to contend.
We users may not pay much attention to it, but Google Calendar, like many similar services, is in a constant battle to retain and improve user numbers.

10. How Many Companies Use Google Calendar?
At this time, the most recent data shows that there are an estimated 398,368 organizations actively using Google Calendar.

You can find many statistical data points on Google Calendar, but looking at usage and demographics can show how people engaged with the service over time.
Nowadays, most people have at least heard about Google Calendar before, even if they’ve never used it.
The name speaks for itself, and there are many statistics that show just how diverse the tool’s user base is on a global scale.
11. Substantial Sharing Capabilities
Another angle that draws individuals and corporations in is the fact that a single Google Calendar can be shared with up to 75 people.
This is a great middle-ground for most projects, whether it’s managed by a single person or small to mid-sized companies.
Larger organizations may run into trouble, but projects that include more than 75 people aren’t always the norm.
This isn’t to say Google Calendar isn’t a good option for businesses with more than 75 employees; it’s simply the cap that’s imposed.
You’ll also find a variety of permission options included.
While some can manage and edit, others can simply view the calendar to stay updated.
It’s an excellent tool for working alongside the many other products and services associated with Google Workspace.

12. It’s a Necessity for Freelancers
Looking into the many different groups of people that use Google Calendar, it seems freelancers think of the service as a sheer necessity.
To explain further, Google Calendar is the second most popular scheduling tool among freelancers as a whole.
This is huge, considering freelance work can be found in almost any industry on the planet.
While some of this stems from the brand name, a majority of it comes down to the features and capabilities of Google Calendar.
Plenty of people might disagree, but Google Calendar trumps much of the competition simply because of its vast integrations with other Google products.
Due to this, the use cases for Google Calendar are quite vast when compared to similar services.
No application remains in the same market position forever.
Google Calendar could rise to the top, or a newcomer could entirely trump its share of the market.
Regardless of which way it actually pans out, Google Calendar will always be a dominant force in this particular market segment.

13. Customers by Company Size
While plenty of individuals use Google Calendar, the platform’s growth is fueled largely by organizations.
We can assume that this is because organizations are more likely to pay for a subscription to Google Workspace, which includes Google Calendar.
Nevertheless, it’s interesting to see the different sizes of companies that utilize Google Calendar on a daily basis.
From an overview perspective, it looks like smaller companies make up a majority of this demographic.
Out of 356,181 companies, 181,700 have zero to nine employees.
The chart below breaks down the total number of companies using Google Calendar by employee count.
Once organizations reach a certain size, internal communications, and project management require a bit more work.
In some cases, Google Calendar hits a cap on how far it can assist a company.
However, there’s no doubt that the service offers more than enough for smaller businesses.
This isn’t to say bigger companies can’t manage just fine with Google Calendar, but you’ll find multiple reasons why they may use it less.
Even with everything Google Calendar is capable of, it’s still somewhat limited in the eyes of sizeable companies.
You might find this hard to grasp from an individual’s perspective, but having hundreds of employees requires multi-level project management systems.

Fast forward to 2019, and this number jumps up to 42%.
