From today "Sunday Feb 3rd", I want to know the closest date for

tomorrow "Monday Feb 4th", I also want to know the closest date for
"Friday" in the past.


With some date in A1, the previous Friday is given by the formula:

=A1-WEEKDAY(A1-6)


On a further step, I need a 2nd formula for the date of the 2nd "Friday"
in the past, ie the Friday before the Friday.

Just subtract 7 from above:

=A1-WEEKDAY(A1-6) -7


Or, if you want to reference only today's date, merely substitute TODAY() for A1 in either of the formulas above

e.g: =today()-weekday(today()-6)
