This is a recording of the Rugrats episode "Chanukah" which is either the premiere or first rerun of the episode.
While commercials are intact on the recording, there is nothing to identify when exactly the recording is from.
There are no screenbugs or on-screen graphics surviving on the recording to indicate a specific date.
The December 7, 1996 rerun belonging to my friend alitek12 contains a promo for the Hey Arnold! Christmas Special which premiered on December 11. This promo is noticeably absent from my recording, leaving me to believe this has to be from December 4 or 5.
