Show or Hide Week Numbers in Calendar auf Xiaomi
Calendar week numbers are useful for planning deadlines, invoices, or shift schedules, but the Calendar app on Xiaomi phones hides this setting inside the app menu instead of the main view. If you never activated it, every week row shows only the dates, forcing you to count from the start of the year manually.
The toggle lives inside the app's own settings, separate from the phone's system settings. Open Calendar, then tap the Menu icon and go to Settings. From there, tap General and look for the Show week number switch. Turning it on adds a small number column on the left side of the month and week views.
Disabling the same switch removes the numbers again if you find them cluttering the layout. The setting applies only to the Calendar app itself and does not change how dates sync with Google Calendar or other accounts. If the numbers still do not appear after enabling the switch, check whether you are viewing the month layout, since some list views do not display week numbers even when the option is active.
