Question

I need to get the Current Sunday date from todays date.

I have tried this but it gives previous week Sunday, expected date is 11 Oct 2020 (today is 13 Oct 2020 )

Here are Today Vs Expected Values

Formula that uses this Date -> Result
10 Oct ->  04 Oct
11 Oct  -> 11 Oct
12 Oct  -> 11 Oct
13 Oct  -> 11 Oct
14 Oct  -> 11 Oct
15 Oct  -> 11 Oct
16 Oct  -> 11 Oct
17 Oct  -> 11 Oct
18 Oct  -> 18 Oct
19 Oct  -> 18 Oct

    =TODAY() - (WEEKDAY(TODAY()) - 1) - 7

Answer 1

With dates in column A , in B1 enter:

=A1-(WEEKDAY(A1)-1)

Answer 2

I have tried this but it gives previous week Sunday, expected date is 11 Oct 2020 (today is 13 Oct 2020)

You don't need -7 . Simply try:

=TODAY() - (WEEKDAY(TODAY()) - 1)

and as the other answer suggests, replace Today() with the desired dates.
