Happy Boxing Day! Yesterday was Christmas Day, and in a few days, it will be New Year's Day. Each holiday season, those two holidays are always on the same day of the week (in this case, Friday). But in 1914, Christmas Day and New Year's Day were on different days of the week. Why?
$\begingroup$ Given the 'real' tag, I can only imagine this has something to do with the Christmas truce of 1914. However, that did not change the day of the week on which Christmas occured (which was a Friday, by the way). $\endgroup$– EarlienDec 26, 2020 at 13:59
Would it be because:
the question references both holidays as being of the same year? 12/25/14 and 1/1/15 would be the same day of the week, but 12/25/1914 and 1/1/1914 are not necessarily.

2$\begingroup$ @Ross the mention of 1914 was a red herring -- and a good one! It caught me for quite a while! $\endgroup$– NL_DerekDec 26, 2020 at 22:51
