Delete a Calendar Event auf Huawei
Calendar entries on Huawei phones running EMUI stay in the app until you remove them manually, even after the appointment date has passed. Deleting outdated events keeps the calendar readable and stops old reminders from popping up.
Open the Calendar app ➔ Choose an event ➔ Tap on Delete. For a single, non-repeating appointment, this removes it right away.
If the event repeats weekly or monthly, EMUI adds an extra prompt: Choose Only this event or All events. Picking Only this event removes just the occurrence you tapped and leaves the rest of the series untouched. Picking All events deletes every past and future instance of that recurring appointment.
Confirm your choice with Confirm with Delete to finish. There is no undo inside the Calendar app, so check which occurrence is selected before confirming, especially with recurring series.
If you only need to change the time or add participants, use the edit option on the event details screen instead of deleting it.
