# Using the LARGE function conditionally

#### Pauljj

##### Well-known Member
Ihave a column (A) with days of the week in and column B with sales figures.

I need to use the LARGE function to work out what the 1st, 2nd etc etc largest sales days are based on the day of the week. So the best Monday, the best Tuesday and so on. does anyone have any ideas on this ?

Thanks

Paul

### Excel Facts

How to fill five years of quarters?
Type 1Q-2023 in a cell. Grab the fill handle and drag down or right. After 4Q-2023, Excel will jump to 1Q-2024. Dash can be any character.

=LARGE(IF(WEEKDAY(A1:A40)=2,B1:B40),1)

The bolded 2 is the number to indicate Weekday.
1=Sun
2=Mon
etc..

Bolded 1 is the # to change for nth largest..

Formula Confirmed with CTRL + SHIFT + ENTER

Are the days of the week true date values?

Hi there Jonmo, I have tried this with minor modification

LARGE(IF(WEEKDAY('2006-2007'!BS\$4:BS\$1500)=2,'2006-2007'!CV\$4:CV\$1500),ROW(A2)-ROW(A\$1))

then confirming with Ctrl + **** + Enter

but I get a #VALUE error ??

Sorry this does work, for some reason my calculations are all very slow, I think its because I have a lot of arrays on the sheet

many thanks for you help
