How to get Previous Working Day base on the OC no-working days calendar?

Hi guys!
As you know,Now we can to set up the process running on the working day,by the corn or the no-working days calendar.
But in some scene,I need get the previous working day. and in this scene,the working day was customed by the OC no-working days.
I think it’s very useful if I can get the previous working day.
