Get the most recent Friday's date SQL

Question

I\'m trying to get the most recent Friday in SQL Server 2008.

I have this. It gets the beginning of the week (monday) then subtracts 3 days to get Friday.

Answer 1

This works for any input and any setting of DATEFIRST:

dateadd(d, -((datepart(weekday, getdate()) + 1 + @@DATEFIRST) % 7), getdate())

It works by adjusting the weekday value so that 0 = Friday, simulating Friday as the beginning of the week. Then subtract the weekday value if non-zero to get the most recent Friday.

Edit: Updated to work for any setting of DATEFIRST.
