Calendar Start Day in Week View

Day day SC Devs,
I need some help with the SC Calendar. I need the start day on the Weekly view to be Monday, not Sunday. I thought I had this working correctly but now I see that it is not. Maybe a recent update broke it, not sure.
Can anyone help direct me in the right direction to fix this? It is very important to my client that the week view start on Monday.
Thanks

Go to Locales->Regional Settings.
Select your region… click Customize… at the bottom you can set the first day

Tada! That fixed it!
Thank you nwdbs!

My pleasure!
