Autofill large increment

[Sanjyn81]

Hello

I have two questions regarding the same spreadsheet. Let me make a small example first:

A                                        B                       C                         D                 E

01-01-2021 00:00              1.23                   01-01-2021

01-01-2021 01:00              1.03                   02-01-2021

01-01-2021 02:00              1.15                   03-01-2021

01-01-2021 03:00              1.47                   04-01-2021

01-01-2021 04:00              1.68                   05-01-2021

.

.

31-12-2021 23:00              

1) In column D I would like to display the MAX value for each day, which is simple enough, "=MAX(B2:B25)" and the next would be "=MAX(B26:49)" and so on. Is it possible to autofill for the entire year?? If I use the usual autofill it only increment by 1 and not 23, which is the idea.

2) Is it possible, in column E, to display the corresponding max value from column D to the value in column A?? In the above example the max value from the day would be "1.68" and then the value in E2 would be "01-01-2021 04:00".

Thanks

@Sanjyn81 You can try MAXIFS() with date+time comparison.

=MAXIFS(B:B,A:A,">="&C1+TIME(0,0,0),A:A,"<="&C1+TIME(23,59,59))

Then try FILTER(), and SORT().

=@SORT(FILTER(A:B,(A:A>=C1+TIME(0,0,0))*(A:A<=C1+TIME(23,59,59))),2,-1)

An alternative suggestion for e.g. Excel 2013 is in the attached file.

@Sanjyn81 First we create a new column (C) with the date of the date-time column, with this formula:

=DATE(YEAR(A1),MONTH(A1),DAY(A1))

Then we find the maximum using this formula:

=MAXIFS($B$1:$B$72,$C$1:$C$72,E1)

 Then we can find the associated time where this maximum occurred using the following formula:

=XLOOKUP(F1&E1,$B$1:$B$72&$C$1:$C$72,$A$1:$A$72)

I made a custom video explaining how to apply these formulas in your case: https://www.youtube.com/watch?v=A14HPBmHcp4

This worked super great, thanks.
