How to sync Xiaomi contacts with calendar: 5 working ways

Synchronizing calendar contacts on Xiaomi smartphones is a useful feature that allows you to automatically add birthdays, anniversaries and other important dates to your schedule. However, many users face problems: duplicate events, lack of synchronization or errors in MIUI. In this article, we will analyze all the current ways of setting up, from standard tools to third-party solutions.

Xiaomi devices offer multiple sync options, including Mi Account, Google, and apps like Truecaller or Sync.ME. We tested each method on Redmi Note 12, POCO X5, and Xiaomi 13T models — all instructions are relevant for MIUI 14/15 and later. If you want friends’ birthdays to automatically appear in the Google Calendar or the standard Xiaomi Calendar app, read on.

Why Contacts Are Not In Sync With Xiaomi Calendar

Before you set up synchronization, it is important to understand the causes of failures, most often problems arise from:

• 🔄 Disabled sync in your Google or Mi Account settings.
• 📱 An outdated version MIUI — firmware MIUI 12 may not have the necessary options.
• 🚫 Application conflict: if multiple calendars are set (e.g. Google Calendar) + Xiaomi Calendar).
• 🔒 Restrictions of rights – some models (e.g, POCO F5) Block background activity to save battery.

Another common reason is that contact data is incorrectly filled in: If the Birthday field only lists a year without a date (e.g. 1990 instead of 15.05.1990), the system will not be able to recognize the event.

⚠️ Note: On devices with Global ROM China ROM Synchronization settings may vary, with Chinese firmware linking some features to Mi Account, while the global version prioritizes Google.

Method 1: Sync through a Google account

The most reliable method is to use Google Contacts and Google Calendar, which works on all Xiaomi devices, regardless of the version of MIUI, and ensures that data is saved when changing phones.

Instructions:

1. Open Settings → Accounts and Sync → Google.
2. Select your Google account (if not, add it through Add Account).
3. Activate the switches opposite Contacts and Calendar.
4. Open the Contacts app, find the right contact and check that the Birthday field is filled in the DD.MM.GYG format.
5. Start Google Calendar – in 5-10 minutes, the event will appear in the Birthdays section.

If events are not displayed, update the data manually:

Settings → Accounts and sync → Google → [your account] → Sync now

Make sure your phone is connected to the internet.

Check that Google’s settings enable Contact and Calendar synchronization

Update Google Contacts and Google Calendar apps in Play Market

Reboot your phone after the changes-->

⚠️ If you are using Xiaomi with China ROM, In order to sync with Google, you may need to install Google Play Services via APKMirror. In some regions (e.g. China), these services are blocked by default.

Method 2: Using the standard MIUI Calendar

Xiaomi smartphones have a built-in Calendar app that automatically adds birthdays from contacts, but this feature only works if two conditions are met:

• 📅 Contacts are saved in your Mi Account (not on Google or on the Internet). SIM-map).
• 🔄 Synchronization enabled in Settings → Accounts and synchronization → Mi Account.

How to set up:

1. Open Contacts. → Settings (⚙) → Contact management → Imports/Exports.
2. Move all contacts to Mi Account (if they are stored on your phone or SIM).
3. Launch the Calendar app and go to Settings → Birthdays.
4. Activate the option to show birthdays.

Important: The built-in MIUI calendar does not sync with Google Calendar. If you want events to be displayed there, use method 1 or 3.

Method 3: Third-Party Synchronization Applications

If the standard methods don't work, try specialized utilities. We tested 3 apps that reliably synchronize contacts with the calendar on Xiaomi:

Recommendation: Sync.ME is best suited for Xiaomi, as it supports integration with the MIUI Calendar.

1. Launch the application and give access to contacts.
2. In the settings, select Synchronization → Calendar.
3. Specify which calendar to add events to (Google or MIUI).
4. Activate the autosynchronization option.

💡

If you have duplicated events after you install Sync.ME, open the app settings and turn off the "Sync with Google Contacts" option, which will prevent conflict between the two data sources.

Method 4: Manual export and import via.vcf file

If the automatic methods don't work, you can manually transfer birthdays to the calendar through a contact file, which is suitable for users who have few contacts or problems syncing accounts.

Step-by-step:

1. Export contacts: Contacts → Settings (⚙) → Contact management → Exports → In memory of the phone (.vcf format)
2. Open the.vcf file on your computer via Google Contacts (https://contacts.google.com) or any text editor.
3. Find the birthday lines (example: BDAY:19900515) and copy the dates.
4. Open Google Calendar on PC, create a new event, and paste dates manually.

It's time-consuming, but it's 100% accurate, and it's convenient to use if you only need to reschedule a few important dates.

⚠️ Note: When manually editing a.vcf file, don’t change the encoding – use it. UTF-8. Otherwise, the Cyrillic symbols will be displayed incorrectly.

Method 5: Automation with Tasker (for advanced)

For users familiar with automation, Tasker is a great tool, and it allows you to create a task that scans your contacts and adds birthdays to your calendar on a schedule.

Algorithm of settings:

1. Install Tasker and AutoContacts plugin.
2. Create a new task with AutoContacts → Query (request to find contacts with the filled Birthday field).
3. Add the Calendar Insert action to create an event in your chosen calendar.
4. Set the trigger to run daily (for example, at 3:00 a.m.).

Example of code for Tasker (simplified):

Profile: "Birthday Synchronization" (Time: 03:00)


Task:




1. AutoContacts Query: Field = BDAY, Save as %birthdays




2. For: %birthday in %birthdays




Calendar Insert: Title="DR: %cn", Start=%bday, Calendar="Personal"




3. End For

This method requires Tasker skills, but gives you complete control over the process, and you can find detailed customization guides on the XDA-Developers forum.

💡

Tasker is suitable for users who need a flexible sync setting (e.g. adding reminders a week before DR or filtering by contact groups).

Problem Solving: duplicates, synchronization errors, calendar missing

Even if you set up the synchronization correctly, you can have a failure, and let's look at the typical errors and how to fix them.

Problem 1: Duplicate events in the calendar

Reason: Contacts are synced simultaneously through Google and Mi Account, and the calendars of both accounts are active.

Decision:

• 🔍 Open the Google Calendar → Settings → Birthdays and turn off unnecessary sources.
• 🗑️ Remove duplicates manually or use the Calendar Cleanup app.

Problem 2: Birthdays are not displayed

Reasons:

• 📵 No Internet (no synchronization is performed).
• 🔕 In the contact settings, the birthday is incorrect (for example, only a year).
• 🚫 Calendar disabled in account settings.

Solution: Check the date format (should be DD.MM.GYG) and force the synchronization update.

Problem 3: MIUI Calendar Resets After Update

After the MIUI update, the calendar settings are sometimes reset to recover the data:

1. Check if sync is enabled in Settings → Accounts → Mi Account.
2. If events are gone, try to return them via backup: Settings → Additional → Backup and Reset → Recover data
