How to generate matched-pairs based on dates?

I have a dataset that includes dates and count of reports. I am tasked with generating matched-pairs using these guidelines:

1. Reports will need to be matched to the week immediately prior to or following. (For example: Jan 23, 2000 will be matched with Jan 16, 2000 and Jan 30, 2000)

2. Holidays must not be included in the final matched-pairs generation.

I have been able to identify the holidays within the dataset but am still stuck on how to generate the matched pairs. Any advice would be much appreciated!
