So, it wasn’t that far back — just 6-years, i.e., 2017.
A 6-year gap between Christmas falling on the same day of the week is fairly common.
The gaps, as you can see from the 2nd diagram above, can be: 5, 6 or 11.
It all depends on how LEAP YEARS intervene. You can also see that from the 2nd diagram. If there is only ONE LEAP year between the years, it is 6 days apart. More than one & actual leap years complicate matters to give us either the 5-year or 11-year gap.
IF you are into calendaring (as I am) you will immediately seize upon that ’11’. 11 is significant. It is 7+4, i.e., the number of days in a week (7) & the number of years between leap years.
Note that we will have a 11-year gap before Christmas again falls on a Sunday.
