Dynamic dates range extend to the associated cells

Hello all,

I am seeking some help, I have a range of 10 cells with dynamic dates and in the cells below dates have some codes associated with each day of the week for my dynamic dates. What I am looking for is, as the dynamic dates changes on each day the codes shall be changed too. For clear idea I have attached screen shot and the file that explains in detail. Any help is highly appreciated.

Not entirely sure I follow - would help to have a variety of examples (for variety of dates), however...

Based on sample - given the repetitive nature of the index it might be wise to store 1 to 10 in a single row and then adapt output results accordingly using this as value as suffix ?

e.g.

A2:
=TEXT(A$1,"ddd")
copied to J2

A19:
=WEEKDAY(A$1,1)+5*(COUNTIF($A$2:A$2,A$2)-1)
copied to J19

Then

A3:
=CHOOSE(ROW(A3)-ROW(A$2),"V","N","LC","HV","HNV","HLC")&A$19
copied across matrix A3:J8

use of row 19 purely for demo - can be wherever simplify modify reference to $19 accordingly
