Wrong Date Calculation - SharePoint
May be because of time zone issue.
You can also try to create Calculated column instead of SharePoint JSON column formatting.You can use below formula for SharePoint Calculated column, in my case it gives correct result now.
=CONCATENATE("(",IF(TEXT(DueDate,"mm/dd/yyyy")-TEXT(NOW(),"mm/dd/yyyy")=0,"Today",IF(TEXT(DueDate,"mm/dd/yyyy")-TEXT(NOW(),"mm/dd/yyyy")=-1,"Yesterday",IF(TEXT(DueDate,"mm/dd/yyyy")-TEXT(NOW(),"mm/dd/yyyy")=1,"Tomorrow",IF(TEXT(DueDate,"mm/dd/yyyy")-TEXT(NOW(),"mm/dd/yyyy")>1,CONCATENATE(TEXT(DueDate,"mm/dd/yyyy")-TEXT(NOW(),"mm/dd/yyyy")," days"),IF(TEXT(DueDate,"mm/dd/yyyy")-TEXT(NOW(),"mm/dd/yyyy")<1,CONCATENATE(TEXT(NOW(),"mm/dd/yyyy")-TEXT(DueDate,"mm/dd/yyyy")," days ago"),""))))),")")Below is the output which I am getting now.

SP1 Check if toLocaleDateString() function in JSON formatting helps to convert both dates in same format & then apply your logic.

Found the root cause of the wrong date calculation of the problem -
e.g. (floor(Number(Date([$DueDate]) - Date(@now))/86400000)+1)==0,'Today'
The value is never = 0
its 0.283.. so the FLOOR value its rounding up is = -1 = hence its always Yesterday
The problem here is - Floor is not able to give the right number - hence all these errors
