How to change the language of the calendar to Xiaomi from Chinese to Russian: 5 working ways

You bought a Xiaomi, Redmi or Poco smartphone with global or Chinese firmware, but the calendar persistently shows dates in Chinese, English or other languages? This problem is familiar to many users - even after changing the system language, some applications, including the MIUI Calendar, can retain original localization. In this article, we will discuss all possible causes and ways to eliminate them, from basic settings to hidden developer parameters.

The Xiaomi calendar is closely linked to the MIUI Calendar and Google Calendar (if you use a Google account), and sometimes it crashes because of a synchronization conflict, an outdated version of the app, or regional firmware restrictions. We will look at solutions for all versions of MIUI 12, MIUI 13, and MIUI 14, including devices with HyperOS (for new models 2026).

Before you start settings, make sure that:

• 📱 The system language of the smartphone has already changed to Russian in the main settings.
• 🔄 Date and time are set automatically (manually exposed parameters can knock down localization).
• 🔗 You have a backup of important events on the calendar (in case of a data reset).

1. Basic Calendar Language Configuration via MIUI

To start with, the simplest method is to check language settings directly in the Calendar app, which works on 90% of global firmware devices, but may not work on Chinese versions of MIUI (more on this below).

Open the Calendar app and follow the following steps:

1. Tap on three points (⋮) top-right.
2. Select Settings (or Settings if the menu is in English).
3. Find the Language section – if it doesn’t exist, move on to the next one.
4. Select Russian from the list. If there is no Russian, try System default.

If the language section is missing, it means that your version of the calendar uses system settings.

• 🔧 Go to Settings. → Additionally. → Language and input.
• 🌍 Make sure the region is set to Russia or Ukraine (for some firmware, it is the region that matters, not the language).
• 🔄 Restart your smartphone – sometimes changes only apply after a reboot.

💡

If there is no Russian in the list of languages, but it is in the system settings, try to delete the calendar cache: Settings → Applications → Application Management → Calendar → Storage → Clear the cache.

2. Change of region of device for correct localization

One of the common reasons why the calendar stays in Chinese is because the smartphone settings are in the wrong region, and even if the language is Russian, some system applications (including calendar and weather) target the country of residence listed in the device profile.

To change the region:

1. Open the Settings. → The phone.
2. Tap a few times on the MIUI version until you have become a developer! (unless the developer mode is activated).
3. Return to the main settings menu and select Additional → For developers.
4. Find the Region option and install Russia or Ukraine.
5. Reset the device.

After changing the region, check the calendar – dates and holidays should be displayed in Russian. If the problem persists, the cause may be limited localization firmware (for example, the Chinese version of MIUI for the domestic market), in which case only reflashing to the global version (for this in section 5).

3. Synchronization with Google Calendar: language setting

If you use a Google Account and sync events through Google Calendar, the display language may depend on your profile settings in Google, not MIUI. This is relevant for users who import events from Gmail or other services.

To change the Google Calendar language:

• 🌐 Open your browser on your phone or PC and go to calendar.google.com.
• 🔧 In the lower right corner, click on Settings (⚙) → Calendar settings.
• 🌍 In the Language and Region section, select Russian and save the changes.
• 🔄 On your smartphone, open Settings → Accounts. → Google and enable calendar synchronization.

After that, the events from Google Calendar will be displayed in Russian, but the MIUI system calendar may still show Chinese holidays.

1. Open the Calendar app on your smartphone.
2. Go to Settings → Displayed calendars.
3. Turn off unnecessary calendars (such as Chinese holidays or Lunar Calendar).
4. Keep only the Main Calendar and Google Calendar.

💡

If you sync your date with Google and it's still in Chinese, check if the MIUI Calendar has a priority for the Chinese lunar calendar.

4. Data cleanup and calendar resetting

If previous methods failed, the problem may lie in the damaged cache or conflicting application data, in which case resetting calendar settings to factory settings will help.

Note: This method will delete all local events (not synced to Google or MI Accounts).If you have important reminders, export them first:

1. Open Calendar → Settings → Import / Export.
2. Select Export and save the file to your device or to the cloud.

Now let's start dumping:

Clear cache | Clear data |Delete updates (if any) |Reboot device-->

1. Go to Settings → Applications → Application Management.
2. Find Calendar in the list and tap it.
3. Select Warehouse → Clear cache and Clear data.
4. If there is a button Remove updates, click it (this will return the application to the factory version).
5. Reboot your smartphone.

Once you restart, open the calendar, it should automatically pick up the system language, and if the problem persists, move to the next section.

5. Flashing to the global version of MIUI (for Chinese devices)

If your smartphone is originally designed for the Chinese market (for example, models with the prefix CN in the title), then you can not change the calendar language by standard methods.

The only solution is to install Global ROM or EEA ROM (for Europe), a process that requires unlocking the bootloader and can result in a loss of warranty, so only execute it if other methods have not worked.

Step-by-step:

1. Unlock the bootloader through the official Mi Unlock Tool (requires a binding Mi Account to the device and wait 7-15 days).
2. Download global firmware for your model from en.miui.com (choose Global or EEA).
3. Install firmware via Mi Flash Tool (for Windows) or TWRP (if supported).
4. Do a reset after firmware (Wipe Data in Recovery).

Once the global firmware is installed, the calendar and all system applications will be in Russian, and it is important that some models (for example, Redmi K50 or Xiaomi 12T) may require re-assigning the Mi Account after the firmware to unlock all functions.

💡

Before you run your firmware, check the model compatibility! Some Chinese devices (such as Black Shark or Mix Fold) don’t have official global firmware, and only custom firmware like Xiaomi.eu will help.

6. Alternative calendars from Google Play

If none of these things worked or you don’t want to risk firmware, the easiest way to do this is to install a third-party calendar from Google Play. Many alternative apps offer more flexible language and sync settings.

The best options for Xiaomi:

• 📅 Google Calendar – full synchronization with Google account, support for Russian language and widgets.
• 📱 Business Calendar 2 – Advanced scheduling and customization.
• 🌙 Etar Calendar – open source software with support for dark theme and minimalist design.
• 🔄 DigiCal Calendar – Integration with weather and reminders, adaptive widgets.

To move events from the standard calendar:

1. Export events through Settings → Import/Export in the MIUI calendar.
2. Install a new application and import the file (usually supported.ics or.csv formats).
3. Set up sync with your Google or Mi Account (if required).

The advantage of this method is that you not only solve the problem with the language, but also get a more functional application. For example, Google Calendar automatically adjusts to the language of your Google account, and Business Calendar 2 allows you to customize the display of holidays for different countries.

Comparison of methods: which way to choose?

To make it easier for you to determine, we have collected the key features of each method in the table:

As you can see from the table, the most reliable way for Chinese firmware is to flash it or install an alternative calendar, and if you have a global version of MIUI, you usually need to change the region or sync with Google.

Frequent Mistakes and How to Avoid Them

When trying to change the language of the calendar, users often encounter common mistakes, and here are the most common ones and ways to solve them:

⚠️ Note: If Chinese holidays (such as Lunar New Year) are displayed on the calendar after the language change, you need to manually turn them off. → Display calendars and uncheck the unneeded options.

Error 1: Language has changed, but dates are still in the year/month/day format

This is not a mistake, but a feature of the regional date formats, to change the order of display:

1. Go to Settings → Additional → Date and time.
2. Select the DD.MM.GYG format manually.

Error 2: After cleaning the data, the calendar became empty

If you don't back up, local events can't be restored. However, events synced to a Google Account or Mi Account will return after re-syncing. To avoid data loss, always export the calendar before resetting!

Mistake 3: No Russian is listed in the list of languages, although the system language is Russian

This means that your firmware is not fully localized.

• Update MIUI to the latest version via Settings → System Update.
• Install a global firmware (see Section 5).
• Use a third-party calendar.

⚠️ Note: On some devices (e.g. Xiaomi Pad 5 or Redmi Note) 11T Pro) after upgrading to HyperOS, the calendar language may be lost, in which case only a complete reset or rollback to the previous version will help. MIUI.
