the "weeks" of the year only appear when you zoom out very far when days turn into weeks, but it would be more convenient / practical to have this info available permanently. Possibly with the ability to use a +/- button to show the Weeks.
What is the underlying problem do you intend to solve with this idea?
Better support of international zone where week numbers are more prevalent
How is the problem being addressed today, if at all?
zoom out to see the weeks, scroll to where you want to go, then zoom back in again to schedule the job
