Sorry, that one issue was a typo on my part, meant to write "column" instead of "row" for days. I have edited that post.

The "1-24" was just an example of another way to handle it depending on his situation. Of course decimals would come in if he needs fractions of an hour. And 0 or NULL for any non-workdays.

Sorry for any confusion. Point was just that your design doesn't have to be limited to BIT.
