Where to look for a calendar in a Xiaomi Redmi 9 phone: all the ways to open and configure

Why users can’t find a calendar on Redmi 9

Xiaomi Redmi 9 smartphones run on the MIUI branded shell, which offers a unique approach to organizing applications. Unlike “pure” Android, where the calendar is usually visible on the home screen or in the application menu, here it can be hidden in non-obvious places. Many users face the problem: the calendar application is not in the list of installed programs, although the task and event planning function in the system is definitely there.

The fact is that MIUI integrates the calendar into other services by default, such as the Mail app or the Weather widget, and Redmi 9 can pre-installe several calendars at once: standard from Google, proprietary MIUI Calendar, and even a calendar from the chip manufacturer (such as Qualcomm), which creates confusion, especially if you are used to a different interface.

In this article, we’ll look at all the possible ways to find and open a calendar on Xiaomi Redmi 9, from standard methods to hidden shell features, and how to add a calendar to your desktop, sync it with your accounts, and what to do if the Suddenly app disappears after the update.

Method 1: Standard Calendar Appendix in MIUI

The most obvious option is to use Xiaomi's built-in Calendar app, but on Redmi 9 it can be hidden or renamed.

On Redmi 9 with MIUI 12/13 firmware, the app can be called MIUI Calendar** and have an icon with a date and clock. If you haven't found it, try an alternative path:

• 📱 If the application is disabled, click "Enable».

💡

If you have multiple calendars (Google, MIUI, Outlook) in your search, choose the one that is synced to your primary account (usually Google or Mi Account).

Method 2: Calendar via the Weather and Clock widget

The MIUI shell is known for bringing multiple features together in a single widget. On Redmi 9, the calendar is often built into the standard Weather & Clock widget that appears on the home screen. Here's how to use it:

1. Find a weather widget on your desktop (usually at the top of the screen).
2. Tap the area with a date (e.g., May 15).
3. A mini-calendar will open with the option of adding events.

If there is no widget, add it:

• 📱 Long pressing on the free space of the desktop → «Widgets».
• 🔍 Find the weather and the clock or MIUI Weather.
• 📅 Drag the widget on the screen and select a size (recommended) 4×2 calendar).

Note that this widget only allows you to view events and add quick reminders. For full calendar work (repeated events, notifications), it is better to use a separate application.

Method 3: Access via Google Calendar

If you use a Google account, your calendar is already synced to your device, even if you can't see its icon.

• 📱 Open the Google Play Store and check if you have a Google Calendar installed (if not, install it).
• 🔍 In the app menu, enter the Google Calendar.
• 📅 If the app is hidden, check the Google folder** on your desktop.

If Google Calendar doesn’t show up but you’re sure it’s installed, try:

Settings → Applications → Application Management → Three dots (⋮) → Show system → Find Google Calendar → Include

Important: On some versions of MIUI for Redmi 9 Google Calendar may conflict with the proprietary application from Xiaomi.If events are not synced, follow the following steps:

1. Go to Settings → Accounts and Synchronization.
2. Select your Google account.
3. Make sure the switch opposite the Calendar is on.

💡

Google Calendar is the most reliable option for syncing between devices. If you use multiple gadgets (phone, tablet, PC), choose it instead of MIUI Calendar.

Method 4: Calendar in the Mail appendix

Few people know, but on Redmi 9, the calendar can be integrated into the standard Mail app (MIUI Mail), which is true if you use corporate email (like Outlook or Yandex) with calendar support.

1. Open the Mail app (the envelope icon).
2. Slip on the menu (three lines) in the upper left corner.
3. Select "Calendar"** or "Calendar".

If this section is missing, check the mailbox settings:

• 🔄 Make sure that the “Calendar Synchronization” option is enabled.

This is a convenient way for those who are actively using mail and want to manage events in one place, but the functionality of such a calendar is usually limited compared to specialized applications.

Method 5: Alternative Calendars and Their Installation

If the standard options don't work, you can set a third-party calendar. Redmi 9 works well.

• 📅 Business Calendar 2 – Extended Business Planning Features.
• 🎨 DigiCal Calendar - Customization of appearance and widgets.
• 🔄 aCalendar – Support for multiple accounts and color tags.
• ⚡ Simple Calendar is a lightweight ad-free app (from the creators of Simple Mobile Tools).

To set an alternative calendar:

1. When you first start, allow access to calendar and notifications.

After installation, we recommend:

Sync with a Google account

Add a widget to the desktop

Set up notifications 10-30 minutes before the event

Disable duplicate calendars (MIUI, Outlook) in synchronization settings

-->

Third-party calendars often offer more features than standard ones, but may consume additional battery due to background synchronization. If you notice a quick discharge, check the energy saving settings in Settings → Battery → Application Selection.

What to do if the calendar disappears after the MIUI update

After a firmware update on Redmi 9, some system applications, including a calendar, may disappear, because Xiaomi sometimes optimizes the shell by removing “extra” services.

1. Go to Settings → Applications → Application Management.
2. Tap it on three points (⋮) → Show system-based.
3. Find com.android.calendar or com.miui.calendar.
4. Click on “Enable” and “Reset” (if necessary).

If the app is not listed, try resetting the settings:

• 🔄 Select “Reset application settings” (does not delete data!).

💡

If the reset does not help, try manually installing it. APK-calendar MIUI. You can download it from reliable sources (for example, APKMirror) by selecting the version for your region (Global/China).

In extreme cases, you just have to reflash your device through Fastboot or Recovery, but it's risky and requires experience. If you're not sure, contact Xiaomi's service center.
