Put date in column on sheet1 into a separate column in sheet2 based on number of occurance

[CalThomps]

This is a spreadsheet for tracking pairings in a couples golf league. The Pairings sheet has the date in column A, and the pairings in however many columns that there are teams. On the Calcs sheet, column A has all of the possible pairings, and column B has the count of how many times each couple has been paired together. I would like to have column C out (Calcs sheet), bring in the all of the dates that each couple has been paired together. So if A and B played together on Dec 22nd and Jan 26th, on the Calcs sheet, I would like C1 to be Dec 22 and D1 to be Jan 26. I have looked at VLOOKUP and INDEX/MATCH until I have a headache. Thank you in advance for any help.

In C1 put this array formula:
(This is an array formula so make sure to use CTRL+SHIFT+ENTER when entering this formula. If done so correctly { } will be added around your formula.

=IFERROR(INDEX(Pairings!$A$1:$A$6,SMALL(IF($A1=Pairings!$B$1:$D$6,ROW(Pairings!$B$1:$D$6),""),COLUMN(A:A))),"")


then drag across and down
