There are a bunch of events who use holiday times for other things.
In German we refer the time from first christmas day to first day of the next year just as “between the years”. (Some other languages do that as well) It seems the English term for that is “twelve nights”. That refers to a lunar calendar (354 days) being a bit shorter than a solar calendar (365.2422 days), which means you need to add leap days after the last day of the year to synchronize it with a solar calendar and the seasons which correlate with it. The roman calendar actually started with march.
Though it wouldn’t be hard to give christmas and the time around it more sciency names. Christmas is based on the winter solstice, the Roman calendar had winter solstice on 25th december and they celebrated the birth of their sun god, where they had parties and exchanged gifts.
