Join Dennis Taylor for an in-depth discussion in this video Using date functions in data validation rules, part of Working with Dates and Times in Excel 2007.
If you are familiar with Excel Date functions, you can use them in a creative…way, along with Excel's Data Validation capability.…In this particular worksheet, there is a Data Validation rule in place in…column B, and that rule is that no entry in column B can be within two…days of the Order Date.…And the way that formula is stated here, =B1>A1+2…refers to all entries in column B. They must be more than two days later than…the Order Date in column A.…
It so happens that in setting this up maybe you weren't thinking about when…that shipping date is.…What day of the week is this? =weekday.…This function will tell us that, and if it's a 1, it means it's Sunday.…Well, you don't do shipping on Sunday.…So you want to make sure that this date is not a Sunday.…Now, its already been entered, so we'll either have to manually take it out or…correct it, but let's say that you want to change the rule to also include…this limitation here, that the weekday is not equal to 1, and furthermore,…maybe you're thinking about Saturdays as well. Maybe you don't do shipping on Saturdays.…
