Improvement
Preceden now provides you with more granular settings for controlling how an event's duration is displayed on your timeline.
For example, if an event spans April 1 - April 19, you now have the ability to specify whether you want Preceden displaying "2 weeks 5 days", "19 days", or even "456 hours".
To choose your preferred units, head to Appearance > Events and adjust the Largest Duration Unit setting:
Hat-tip to Joty, one of Preceden's customers, for suggesting the improvement.
