Many users who have just bought a new smartphone often find themselves confused by the MIUI or HyperOS interface. The seemingly simple task of seeing a date or marking a meeting turns into finding a needle in a haystack. This is because Xiaomi’s shell has its own unique application grouping logic, different from pure Android. Standard utilities are often hidden inside system folders or have altered icons, which confuses those who used other brands’ devices before.
But don't worry, because Calendar is an integral part of the system and doesn't disappear without your knowledge. In this article, we'll take a look at all the possible places where the scheduler icon might be hiding, and we'll look at how to quickly access it through lock screens and widgets, and you'll learn not just to find the program, but also to customize it to your needs, adding important events and holidays.
We'll also talk about the technical aspects of how this tool works in the Xiaomi ecosystem, for example, many people don't know that the built-in calendar is closely linked to the Mi Account and can sync data between devices. Understanding these connections will help you avoid losing important records when you change your phone or reset your settings. Let's figure out where to look for this important tool and how to make it as comfortable as possible to use it.
Search for a standard application in menus and folders
The first place to look is the full menu of all installed programs. On Xiaomi smartphones, it is called by a swipe up from the bottom of the screen or a three-dot/stripe button in the dock bar, depending on the style chosen. Unlike some other shells, applications are often sorted not only by alphabet but also by categories created by the system. The calendar icon is usually a white sheet with the red digit of the current date, but its design can vary depending on the the the theme of the design.
Often users can't find the program because it accidentally landed in the Tools system folder. There's a pre-installed group in the MIUI shell where the utilities automatically fold: a voice recorder, a scanner, a calculator, and, in fact, a calendar. Take a close look at the desktop: if you see a folder called Tools or Tools, click on it. There's a 99% chance that the app you want is there.
If manual search takes too long, you can use the built-in search engine. Swipe down your desktop (or click on the magnifying glass in Google search bar) to trigger a global search. Type the word "calendar" or "calendar." The system will instantly show the app icon, and also prompt you to launch it or open settings. This is the fastest way if you don't want to waste time flipping screens.
⚠️ Note: If a title search is not yielding results, it may have been removed or hidden in Guest/Second Space mode.
And you should also mention the Hidden Apps feature, which allows you to hide sensitive software, and if you or someone else has used this option before, the icon may have disappeared from public access. To check this, open the Security app, go to the settings, and find Hidden Apps. If there's a calendar, you can return it to a prominent place.
Adding widgets to the desktop
For many users, it is more important to not run a separate application, but to see the date and upcoming events directly on the home screen. The calendar widgets on Xiaomi are different functionality and design. To add them, you need to make a long tap (tap and hold) on the free desktop area. In the bottom menu that appears, select “Widgets” (or “Add widgets”).
In the list that opens, look for the Calendar section, and you can see a range of options, from just showing the current date to a big scheduler with a to-do list for the week, pick the right size and style, drag it to your desktop, and some widgets allow you to change color and transparency right at the time of setting up, which is convenient for customizing the interface to your theme.
The Events widget is a special focus, and it not only shows the number, but also displays the meeting headers that are scheduled for today. If you use Google Calendar in parallel with the standard one, make sure that the widget is set to display the desired data source. In the widget settings (usually available with a long click on it), you can select an account to sync.
☑️ Setup of the calendar widget
If standard widgets seem boring to you, the MIUI theme store offers hundreds of alternatives. However, beware: third-party widgets can consume more battery power or require unnecessary resolutions.
Set up display of holidays and weekends
One of the most common problems is that there are no red dates on the calendar. By default, some regions may not display public holidays in the country where the phone was purchased, or they may be disabled in the settings. To fix this, open the calendar app, click on the three dots in the upper right corner, and select Settings.
In the settings menu, find the option “Holidays” or “Display holidays.” Here you can select the country you want to see. For users from Russia, Kazakhstan or Belarus, you often have to manually turn on the corresponding flag if it is not automatically determined by the appropriate flag. SIM-You can also include the phases of the moon and folk signs, which can be useful for planning garden work or photography.
It’s important to distinguish between holidays and subscriptions. Xiaomi’s calendar often features aggressive ads for news subscriptions and horoscopes that clog up the grid, and the same settings menu recommends turning off all unverified event sources, leaving only personal accounts and public holidays, to make the interface cleaner and clearer.
| Parameter | Where to find out. | Recommendation |
|---|---|---|
| Holiday country | Settings → Holidays | Selecting a country of residence |
| Beginning of the week | Settings → General | Monday (standard for CIS) |
| Moon phases | Settings → View | Insert for convenience |
| Promotional subscriptions | Settings → Subscriptions | Shut it down. |
⚠️ Warning: After updating the firmware, the holiday settings may reset. Always check this item after a major system update. MIUI.
Also, check the format of the date. Some global firmware versions have the default American format (month/day/year), which can cause confusion, and you can change this in the general settings of the phone system, under the "Date and time" section, by selecting your region.
Sync with your Google and Mi Account
A modern smartphone is impossible without cloud synchronization. Xiaomi has two main events storage services: Mi Cloud and Google Calendar. The standard app can work with both at the same time, but you need to set them up correctly. Go to Settings of the phone → Accounts and Sync.
Make sure that your Google account is marked with a Calendar checkmark, which ensures that all appointments created on your computer or tablet will instantly appear on your phone, and you should also set up your Mi Account if you plan to switch to other devices of the brand in the future. Double sync can create duplicate events, so you should choose one primary service.
If you use corporate email or other services like Yandex or Outlook, you can add them to your system, and if you add a new account, the system will ask you what data to sync, and you should select a calendar, otherwise the events from your workmail will not appear in the general scheduler grid.
What to do if events are not synchronized?
Remember that deleting your account from your phone settings will cause all related events to disappear from the app, so make sure that important data is stored in the cloud before resetting or selling your phone.
Alternative apps from Google Play
If Xiaomi's standard calendar seems too overloaded or functionally poor, there's nothing stopping you from installing an alternative. Google Play offers dozens of great solutions. One of the most popular is the Google Calendar, which is minimal, integrates well with Gmail and has no ads.
For those who like visual beauty and planning, applications like Business Calendar 2 or Simple Calendar are suitable, offering flexible customization of species (year, month, week, day), color coding of categories and widgets that look much better than standard ones. Installing a third-party application does not require removing the system one - they can work in parallel.
When you install a new calendar, the system may ask which application to use by default to open links like “” or when using voice assistant commands. Choose the one you plan to use constantly. However, even using third-party software, do not turn off the system calendar completely, since some system services may access it to display the date in the notification curtain.
💡
Use the Google Discover widget to the left of the home screen to see calendar events without running apps, saving time and battery life.
It’s important to give the new app all the permissions you need, especially access to contacts (for birthdays) and notifications, and without that, the functionality will be cut down, and you may miss an important reminder of a colleague’s birthday or meeting.
Solving problems: calendar is missing or notifications are not working
There are times when the icon seems to be there, but the app doesn't start, or worse, appointment notifications have stopped coming in. Often the problem is the aggressive MIUI energy saving system. It can kill the calendar process, considering it inactive. To fix this, pinch the calendar icon, select About Application → Battery, and set the No Limits mode.
If the calendar is gone and not even in search, it may have been turned off in the app settings. Go to Settings → Apps → All Apps, search the Calendar (or Calendar) list and click Enable if the button is active. It’s also worth checking if it’s hidden in parental controls or the child’s profile if such features are configured.
In case notifications don't work, check not only battery settings, but also permissions. The About app menu → Permissions should allow notifications and auto-start access. Without auto-start, the app may not start in the background at the appointed time.
💡
The main reason for missing notifications on Xiaomi is aggressive energy saving, and be sure to put the status "No restrictions" for important app planners.
⚠️ Note: Do not clear calendar app data through the Memory menu unless you have sync set up.This will delete all locally stored appointments that have not been sent to the cloud.
If nothing helps, create a new user on the system and check if there is a calendar there, if there is one in the new profile, then the problem is that your main profile settings are damaged, and you may need to reset your phone settings.
