Changing working hours in forecast view
 

Just wondering is there any method to change the default working hour (from 8am to 6pm) in the forecast view? for example, setting it from 10am to 10pm?

Thank you for your help:)

Tap the eyeball icon while in Forecast view and you'll get the options.

Yes, you can set the times for the bar on the forecast view. Just go into the Forecast view, open up the view settings (little eye in to menu bar), set the calendar start and stop times there.
