How do i create a dynamic schedule in excel?

Do the following to create a dynamic monthly calendar in Excel. For the same template as above, we'll create a dynamic calendar. Of course, all start and end dates would be close and should be later than the reference date of the rotation program by design to appear on the schedule. I want to be able to take all the cells between the start and end date and shade them in each row, then, when the last cell or the end date is complete, I want to use column F, schedule the shutdown time and skip that number of days and then start shading the next cell for the number of ON days of the column D and then keep continuing until those days are completed and then start the program OFF again until it ends, then repeat ON and OFF, then ON and OFF until the cell year is complete.

We discussed creating a simple and dynamic calendar template in Excel using formulas with a downloadable Excel sheet.
