How to hide the key / ID in calendar view?

[Dominik-Stephan Betschart]

Hello there!

Does anyone know how we can hide the ID / key (in this case the "REDAK-588" etc.) in calendar view?

It takes up too much valuable space and the title/subject is far more important for our calendar view to read than the ID / key. Thank you!

Unfortunately, Jira's native calendar view (such as in Team Calendars or Advanced Roadmaps) doesn't currently offer built-in customization to hide issue keys from display titles.

But  THERE ARE a couple of potential workarounds:

1. You could consider creating Custom Event types or manually entering summary-only events for visual clarity—though this requires extra management.
2. You might consider voting or raising a feature request on Jira's public issue tracker (Jira Cloud) if this display customization is CRITICAL. 

HOPE THIS HELPS.
