Which of the following is NOT a use of date functions in Excel?

Sorting a list alphabetically is not a function associated with date functions in Excel. Date functions are specifically designed to manipulate and analyze dates in various ways, such as calculating age by comparing a birth date to the current date, calculating the number of days between two specific dates, and extracting different components of a date, such as the year, month, or day.

In contrast, sorting a list alphabetically deals with text or numerical values, utilizing functions related to sorting algorithms rather than date manipulation. Therefore, the option correctly identifies an action that does not fall under the category of date functions in Excel.
