Owners of Xiaomi, Redmi and POCO smartphones often face a situation where holiday dates saved in the phone book are not automatically displayed in the system scheduler, a problem that is especially relevant when switching from other operating systems or after resetting to factory settings, when data synchronization requires manual activation.No reminders of important dates can lead to awkward situations, so setting up accounts correctly is a priority.
The modern MIUI shell and the new HyperOS have built-in mechanisms that allow you to link events from the contact list directly to the calendar widget. However, these features are often hidden in the depth of the menu or disabled by default for the sake of saving traffic and battery power. Understanding the logic of the Google account and local services from Xiaomi will help you quickly automatically display all the celebrations.
In this article, we will take a look at all the possible ways to integrate data, including using standard system tools and third-party applications. You will learn why automatic import may not work and how to force an update to the event list.
Verification of contact sources and their status
The first step before any synchronization is to analyze where exactly the phone numbers and names of your friends are physically stored. In Xiaomi smartphones, contacts can be located in three main places: SIM-It is critical for calendars to function properly in an account that supports event synchronization, such as a Google profile.
If your records are only stored locally on your phone or SIM card, the system may not see any calendar events. Local contacts often do not have a field for annual event repetition, which is automatically pulled up to the scheduler.
💡
Before mass transfer of contacts, make a backup through the Import/Export menu to avoid accidental loss of numbers in the event of a network failure.
To check the source of a particular record, open the Contacts app, select a person, and look at the top of the screen or the contact properties, and it will indicate the account to which it is attached. If it says Phone or SIM, you need to change the storage location. This is the basic requirement for the automatic event creation function from the birth field.
- 📱 Open the Contacts app and go to the display settings.
- 👤 Select a contact and check the “Account” or “Where is saved” field».
- ☁️ Make sure you select a Google or Mi Account profile, not local storage.
- 🔄 If necessary, use the “Move Contacts” function to change the source.
Set up synchronization of Google Contacts
The main driver of birthday transfer in the Android ecosystem is Google. Even if you use Xiaomi's shell, Google Contacts is the most common source of truth for the calendar. For birthdays to appear in the scheduler, you need to activate the appropriate switchboard in the system sync settings.
Go to Settings → Accounts and Sync (the path may vary slightly depending on the version of MIUI). Find your Gmail account and click on it. Make sure the switch opposite Contacts is active. Without this option, the phone will not request updated information about holiday dates from servers.
⚠️ Note: If the dates did not appear immediately after the synchronization was enabled, wait. 5-10 minutes with Wi-Fi enabled. Google servers take time to transfer the data packet to the device.
Also worth checking is the settings of the Google Contacts app itself. Go to the menu inside the app and select “Sync settings” where you can set up which contact groups to share data in detail, and sometimes users accidentally turn off sync for certain shortcuts, so birthdays from these groups are not imported into the calendar.
☑️ Checking Google Syncs
Integration with the Xiaomi Calendar app
Once the data is updated in the contacts, you need to make sure that the Calendar app on Xiaomi has permission to see it. The standard app often filters events by showing only those created manually or that came by email. Birthdays require special attention in the display settings.
Open the Calendar app and click on the menu icon (usually three bars or dots). In the calendar list, find the section associated with your contacts or Google. There should be a birthday item or a Birthdays item. Make sure the tick is ticked against it. If that item is missing, it may not have recognized the dates in the contacts yet.
In some versions of HyperOS firmware, settings may be hidden deeper. Go to Calendar Settings → Calendar Management. This shows a complete list of all the connected event sources. If you see your Google account, open it and check if the birthday sub-clause is activated, which ensures that events will be displayed on a common timeline.
- 📅 Run the standard Calendar app on the home screen.
- ⚙️ Go to the event display settings (eye icon or menu).
- ✅ Find the list of “Birthdays” and activate the switch.
- 👁️ Check if the tick is worth the event display from Google Contacts.
Using Mi Cloud for Mi Account Owners
Users who are actively using the Xiaomi ecosystem often store data in Mi Cloud. This cloud storage also knows how to sync contacts and calendar, but works independently of Google services. If your contacts are tied to Mi Account, the algorithm of actions will be slightly different from the standard Android script.
You need to log in to Settings → Mi Account → Sync. Make sure that contacts and calendar sync are enabled. The Mi Cloud feature is that it can create a separate local birthday calendar that doesn't mix with Google's calendar, which is convenient for separating personal and work events, but requires checking both sources.
Importantly, when using Mi Cloud, the dates of birth may not automatically be pulled up unless the contact itself has a special "Birthday" field filled in, not just text in notes. The system analyzes the data structure, and if the format does not match the expected, the import will not occur. Check a couple of contacts manually to make sure that the fields are filled in correctly.
⚠️ Note: When you use Google and Mi Cloud at the same time, you may experience duplicate events. If you see the same birthday twice, turn off the sync of birthdays in one of the services.
Solving problems with duplicates and display
A common problem when combining data from different sources is the appearance of duplicates or, conversely, the disappearance of events. If after all the settings you see two holidays on the calendar, or none, you will need to manually clean and reconfigure the filters.
To start, try clearing the Contacts and Calendar app cache. Go to Settings → Apps → All apps, find the app you want, and select Clear Cache. Don't confuse it with Clear All Data, as this can remove local settings, although contacts from the cloud must be restored. After clearing the cache, reboot your smartphone.
If you have duplicates, check if you have Google contacts and SIM-You can see these as two different events, and use the "Joint Duplicates" function in the Contacts app to bring the records together to a single denominator, which will make it easier for the synchronization algorithms to work.
Why can the dates be shifted by one day?
The table below shows the main reasons for the absence of birthdays and how to eliminate them:
| Problem. | Probable cause | Decision-making |
|---|---|---|
| Birthdays are not on the list | Contact synchronization disabled | Enable synchronization in Google account settings |
| There are events, but without reminders. | Notified time not set up | In the calendar settings set the default reminder time |
| Duplicate events | Two sources are active (Google + Mi Cloud) | Disable one of the sources in calendar management |
| Wrong holiday date | Error in contact field or time zone | Correct date in contact and check time zone setting |
Alternative methods and third-party applications
If the standard means of configuring the transfer fails, specialized applications from the Google Play Store come to the rescue. There are utilities designed specifically to convert contacts into calendar events, such as the Birthday Import Tool or Contacts to Calendar, which allow you to flexibly adjust import rules, ignoring the system limitations of Xiaomi.
These applications often have a more advanced filtering interface, so you can choose whether to import only contacts with a specific label, or set a standard reminder time for all events you create (e.g., 1 week and 1 day), which is especially useful for those who like to plan gifts in advance.
💡
Third-party converter apps are “heavy artillery” that helps when Google’s standard sync fails or malfunctions with a particular version of MIUI.
When using third-party software, keep data security in mind. You give the app access to your entire phone book. Choose only proven programs with high ratings and a lot of reviews. Once the successful import and calendar events appear, the app can be revoked in the privacy settings.
- 📥 Download a proven app to import contacts from the Play Market.
- 🔐 Provide the necessary permissions to access contacts and calendar.
- ⚙️ Set up the rules for creating events (reminder time, repeat time).
- ▶️ Start the import process and check the result in the calendar.
