I need a formula or a macro to help automate a grade sheet's dates.

We have class every Monday or Wednesday only. I would like to `vlookup`

from an input table of each quarter's date range, for example, Sept. 10 - Oct 24. The code should auto-insert the date of every Monday and Wednesday in a row at the top of my grade sheet.

Every year I use the same Excel workbook I built to average and rate the grading with no problem, however I can't seem to get this one right. Currently I have to enter each date by hand.
