Hello. First of all thanks for this app. Here is a suggestion from personal habits.

I am used to using the 12-hour system to check the time, but the schedule time displayed by Calendar seems to be fixed at 24 hours; maybe Calendar can automatically synchronize the settings of the system or provide relevant options?
