Sunday
Sunday.
Yes, Christmas is always on December 25th every year.
It doesn't. The 25th of December 2016 is a Sunday. It was on a Friday in 2015 and as 2016 is a leap year, it skips an extra day and is on a Sunday in 2016, not Monday. It will be on a Monday in 2017.

The last time October 25 fell on a Sunday was in 2009.

Easter Sunday has fallen on April 25th in the years 1734, 1886 and 1943. Easter Sunday is due to fall on this date again in 2038.
There is a pattern in the way days fall on dates from year to year. By examining particular combinations of days and dates you could find all sorts of patterns like the one you mentioned. There is no more detailed explanation than that. It is just the way it happens. If you take the most recent occasion it happened, when Christmas Day was on a Thursday in 2008, with Christmas Day being on Sunday in 2005 and 2011. In this case it is a 6 year period from the Sunday to the Sunday, during which there is one leap year. One year is skipped, which is the Wednesday, and so the next Sunday comes around 6 years later.

The days that the other Christmas Days in that period will be on will also be the same. The previous occasion where Christmas Day was on a Sunday in a leap year would have been in 1980, and before that in 1952 and before that in 1924. You can see there is another pattern there, a 28 year gap. Day and date combinations are full of patterns if you examine them. Your example is just one of them.
