Preceding 2011 was 2005 and after 2011 the next time such a year will occur will be 2022. It will not be 2016 since 2016 begins on Friday whilst 2011 began on Saturday. Christmas in 2016 may well fall on the same day as Christmas 2011, but onlythe months from March to December in 2016 match perfectly with 2011, therefore 2022 will both start and end on the same days as 2011 making it the next identical calendar.
The next year Christmas day will fall on a Tuesday is 2018.
