A3 =IF(A1="","",YEAR(A1))

B3 =IF($A$1-WEEKDAY($A$1,3) +((ROW()-3)*7) <= $B$1-WEEKDAY($B$1,3), ISOWEEKNUM($A$1-WEEKDAY($A$1,3)+((ROW()-3)*7)), "")

C3 =IF(DATE(YEAR(B1),MONTH(B1),DAY(B1))>=DATE(YEAR(A1),MONTH(A1),DAY(A1)),IF(A1<>"",A1,""),"CHECK DATE RANGE")

D3=IF(DATE(YEAR(B1),MONTH(B1),DAY(B1))>=DATE(YEAR(A1),MONTH(A1),DAY(A1)),IF(B1<>"",MIN(DATE(A3+1,1,2),(DATE(A3,1,1)-WEEKDAY(DATE(A3,1,1),2)+B3*7)),""),"CHECK DATE RANGE")

I Want result as below

Answer 1

These formulas will work in Row 3:

A3  =IF(ISNUMBER($A$1),YEAR(A1),"")
B3  =IF(ISNUMBER($A$1),WEEKNUM($A$1,2),"")
C3  =IF(ISNUMBER($A$1),$A$1-WEEKDAY($A$1,2)+1,"")
D3  =IF(ISNUMBER($A$1),$A$1+6-WEEKDAY($A$1,2)+1,"")

Starting in Row 4, enter these formulas, then use the auto-fill cursor (select cells A4:D4, then click and hold on the lower-right corner icon of the selection box) to copy-fill as many rows down as you need.

A4  =IF(ISNUMBER($D3),IF(($D3+1)<$B$1,YEAR($D3),""),"")
B4  =IF(ISNUMBER($D3),IF(($D3+1)<$B$1,WEEKNUM($D3,2),""),"")
C4  =IF(ISNUMBER($D3), IF( ($D3+1)<$B$1,  $D3+1,""),"")
D4  =IF(ISNUMBER($C4),$C4+6,"")

By the way, you mentioned in your post that you wanted Monday as the start of the week. So I used the value 2 in both WEEKNUM and WEEKDAY . Use a different value for other days if needed.
