Frequently Asked Questions

Question: Is there a LIKE function in Excel similar to the one in Access? I'm trying to write a formula equivalent to the following:

=if(D14 like "*Saturday*", Now()+2, Now()+1)

Where cell D14 is a date value formatted as Saturday, August 27, 2005.

Answer: Since your value in cell D14 is a date value, you can use the WEEKDAY function to determine which day of the week it is. In this case, you are looking for a Saturday. The WEEKDAY function will return a value of 7 when the date falls on a Saturday.

Try using the following formula:

=if(Weekday(D14)=7,Now()+2,Now()+1)
