Does enabling week numbers change how dates or events are displayed?

No, it only adds a small number next to each row in the month and week views. Events, reminders, and dates stay exactly as they were.

I use Google Calendar instead of the Oppo calendar app. Does the same setting apply?

No, Google Calendar has its own separate settings menu for week numbers. The path described here only works inside the pre-installed Oppo calendar app.

Will this setting reset after a software update?

Usually not. The week number preference is saved per app and normally survives regular updates, but a full reset of the calendar app data would remove it.

Oppo: Show Week Numbers in the Calendar App

If your Oppo calendar does not show week numbers next to the dates, the setting is simply switched off by default. This option lives inside the calendar app itself, separate from the general phone settings, which is why most people never stumble across it. Without it, planning by calendar week for work or school becomes harder than it needs to be.

Show or Hide Week Numbers in Calendar auf Oppo

On Coloros, the calendar app ships with week numbers turned off. That is a setting inside the calendar itself, not something buried in the general system settings, which explains why the option is easy to miss.

To turn it on or off, open the calendar and follow this path: Tap on Calendar ➔ Open the Menu ➔ Tap on Settings ➔ Tap on General ➔ Enable or disable Show week number.

Once enabled, every monthly and weekly view gets a small number next to each row, showing the calendar week for that stretch of days. This is useful for anyone who plans around ISO week numbers, for example in shift schedules, school terms, or project deadlines.

If the toggle does not stick after switching apps, check whether you are using the built-in Oppo calendar or a separate Google Calendar app, since each app manages this setting independently.

Turning the option off again removes the numbers from every view immediately, no restart needed.

Frequently asked questions
