Grouping date based on week | Excel

Question

List Image

Result That I Hope

I need to figure how to group list of date.

Date Formula : "mm/dd/yyyy"

i've tried using : 1. =A1 + 7 . it returns 43113 2. =A1 + WEEKDAY(A1;1) . it returns 43113

Is there any formula to calculate date?

I have an logic for grouping

=IF(A2<(A2+WEEKDAY(A2;1)) ;Return the number of the first week;Nested IF)

Target : there are 5 groups

• june 1-7
• june 8-14
• june 15-21
• june 22-28
• june 29-5

Answer 1

如果所需组之外没有日期，这是所有数据的正确嵌套 IF 公式。

=IF(AND(I7>=43252;I7<=43258);1;IF(AND(I7>=43259;I7<=43265);2;IF(AND(I7>=43266;I7<=43272);3;IF(AND(I7>=43273;I7<=43279);4;5))))
