Day (1..n): !!VRv1:Sc;
Day (0..n): !!VRv1:Sc -1;
Day of the month (0..27): !!VRv1:Sc -1 %28;
Week of the month (0..3): !!VRv1:Sc -1 %28 :7;
Week of the month (1..4): !!VRv1:Sc -1 %28 :7 +1;

Can I ask please for "day of the week"? It is the only one missing from the list and I remember there was a quirk on day 7 with the code from help.
