@KylinShinlyLin, thank you for the contribution! Could you also please add a configurable flag in both the day view and week view to control whether the 00:00 hour is displayed?

Some users may prefer not to show the 00:00 hour in the calendar, so providing an option to hide or show it would offer greater flexibility and better support different use cases.

Additionally, it looks like one of the checks is currently failing in this PR. We’ve updated the master branch to address this issue. Please rebase your branch on master and ensure that all checks pass.

Thanks again for your work and continued support!
