A meme that people were doing on New Year's Eve 2020 instead of making it January 1, 2021.
Of course 2021 was still a very bad year, despite the fact that some said that it was gonna be a good year, just because of how terrible 2020 was. However, it would not be good if December 32, 2020 was a thing, because literally no one needed another day of 2020, or at least no one in their right mind, anyway.
When New Year's celebrated, but in another continent it is still December 31th because of the different time zones. The variation of time from January 1st and December 31th can be named as "December 32th" a popular name given to this changeless deviation on the temporal length.
