    2017 is correct, 2028 is not.

    Because weeks have seven days, and leap year is on a four-year cycle, the days and dates realign on an 11, 11, 6-year pattern.

    The next 2023 alignment is 2034 (11), then 2045 (11), then 2051 (6).

    Edit: I realize you are referring to the month of December only, and not the entire calendar year. In which case December 2028 does happen to have the same dates because 2028 will be a leap year.

    Funnily enough, Arthur’s Perfect Christmas was released in 2000, also a leap year. So that “calendar year” doesn’t completely match 2023 either.
