What I want to do is so you have a list of random dates, it will never be the same so it has to be a universal formula, but you get any date, any date of the year and then e
This formula will give you the Thursday following a date in A1
=A1+7-WEEKDAY(A1+2)
If A1 is a Thursday it returns that date, if it should be A1+7 if A1 is Thursday then change to this version
=A1+8-WEEKDAY(A1+3)
