How to Clean Your Xiaomi Calendar Completely: Delete All Activities in 5 Minutes

An eventful calendar on Xiaomi is a problem that both students and office workers face after a session. Old meetings, reminders of overdue tasks, and duplicating holidays clutter the interface, preventing them from planning a new day. Unlike an iPhone or Samsung, where cleaning the calendar is intuitive, MIUI's firmware hides this feature in non-obvious sections.

In this article — 5 Proven ways to remove all activities at once, including methods for synchronized Google accounts and local calendars. We'll discuss how to avoid the "failed to sync" error, why some events remain after reset, and what to do if the Mi Calendar calendar freezes when it is deleted by mass. MIUI 14/15, They can clean up events without losing important reminders.

If you use Xiaomi as a working tool, a clogged calendar can cause missed deadlines. For example, old repetition events ("Weekly Planning") continue to duplicate even after manual removal. In such cases, deep cleaning is required, which is not offered by standard settings. Next, step-by-step instructions taking into account the features of different versions of MIUI and models (Redmi Note 12, POCO X5, Xiaomi 13T, etc.).

1. Remove via MIUI Calendar Settings

The most obvious, but not always working, way is to use the built-in Mi Calendar app tools, which are suitable for local calendars (not synced with Google), but may not work if events are added through third-party services (Outlook, Yandex).

To clear the calendar:

1. Open the Calendar app (Date Icon).
2. Tap it on. ⋮ (three points) in upper right corner → Choose Calendar Management.
3. Click on the calendar you want (for example, Personal or Work calendar).
4. Scroll down and select Delete all events.

⚠️

Note: If the Delete All Event button is inactive (grey), then the calendar is synced with Google Account.

On some models (POCO F5, Xiaomi 12 Lite), instead of the delete button, you can display Reset Calendar. This option only removes the display settings (colors, notifications), but not the events themselves. To avoid confusion, check the version of MIUI in Settings → About phone.

2.Reset via System Settings (for MIUI 14 and later)

If standard deletion doesn’t work, try resetting your calendar through system settings, which deletes all local events but doesn’t affect those synced to Google or other accounts.

Instructions:

1. Go to Settings → Applications → Application Management.
2. Find the calendar (or com.miui.calendar) in the list.
3. Slip it on the vault. → Clear the data.
4. Confirm the action by pressing OK.

⚠️

Warning: After this operation, all notification settings and calendar color tags will be reset to factory reminders, and if you used custom reminders (like the sound of Alarm 5 for important meetings), you will have to reset them.

On Redmi with MIUI 13 and older, the path may be different:

Settings → All settings → Applications → Calendar → Memory → Clear data

Save important events manually (screenshots or export)

Check if your calendar is synced to Google

Close all background apps (especially messengers)

Make sure the battery is charged more than 30 times%-->

3. Mass removal via Google Calendar

If your calendar is synced to a Google Account, previous methods won’t work — events are stored on Google servers, not in your phone’s memory, in which case you need to clear the calendar through the web version or Google Calendar mobile app.

Method 1: Through a browser on a PC or phone

1. Open calendar.google.com in your browser.
2. In the left menu, find the calendar you want (for example, address@gmail.com).
3. Press on. ⋮ near-name → Settings and sharing.
4. Scroll to the block Remove the calendar → Delete forever.

Method 2: Using a mobile application

1. Open the Google Calendar on your phone.
2. Tap on. ☰ (line) → Choose a calendar.
3. Press. ⋮ → Settings → Delete the calendar.

⚠️

Note: Deleting a calendar through Google permanently deletes all events, including recurring ones. If you want to save individual appointments, export them to.ics first (in calendar settings). → Exports).

If events still appear in Mi Calendar after deleting, perform forced synchronization:

Settings → Accounts → Google → Your account → Sync → Calendar (on / off)

4.Use of ADB for deep cleaning (for advanced)

If standard methods have failed and the calendar is still full of events, you can use the ADB debugging bridge. This is suitable for users willing to work with the command line.

Instructions:

These commands will completely reset the settings and data of the Mi Calendar and Google Calendar. After the phone is rebooted, all events will disappear, but synced with Google will return the next update. To avoid this, pre-delete the calendar through the web version (see section 3).

⚠️

Note: On some models (Xiaomi 13 Pro, POCO F4 GT) after the command pm clear, the calendar widget may disappear from the home screen. To return it, restart the phone and add the widget again.

💡

If so, ADB-Commands calendar stopped opening, reset its cache through Settings → Annexes → Calendar → Clear the cache. It won't delete the event, but it will restore the performance.

Alternative methods: third-party applications

If the built-in MIUI tools don't work, you can use third-party utilities. We tested 3 apps that safely delete events without root rights:

Before using third-party apps, back up your calendar:

1. Open Mi Calendar → ⋮ → Exports.
2. Select the.ics format and save the file to Downloads or Google Drive.

⚠️

Note: Apps like Calendar Cleaner request access to your events, and do not install them from unverified sources (like apkpure.com) to avoid data leakage.

6 What to do if events return after deletion

Sometimes, users find that after cleaning the calendar, events return within hours or days, for three reasons:

• 🔄 Auto Sync: The calendar is linked to the account (Google, Mi Account), and events are recovered from the server. Solution: disable sync before deleting.
• 📅 Repeated Events: Meetings with the Repeat Daily/Weekly setting can be restored automatically.Solution: delete them via the Google Calendar web version.
• 🤖 System reminders: Some events (e.g., "Contact Birthday") are added automatically from other apps (Contacts, Mi Fit).Solution: check the settings of these apps.

If the problem does not go away, perform a full synchronization reset:

1. Go to Settings. → Accounts.
2. Select a problem account (Google or Mi).
3. Turn off calendar sync.
4. Remove all events manually (see Section 3).
5. Turn the sync back on.

💡

If events keep coming back, check if your phone has TickTick, Todoist apps installed, which can automatically add tasks to your calendar.
