There would have been one in 2004
IF NOT for it having been a Leap Year.
Christmas, per the name ‘LEAP’,
jumped over Friday & took place on Saturday.


Last time we had Christmas, i.e., December 25th, on a Friday was in 2015 — 5-years ago.

6-year gaps are common. The cycle as to when the same date falls on a given day (e.g., Monday) goes in 6-5-6-11 cycle. You can see that in the image above — as to when Christmas has fallen on a Wednesday.

This 6-5-6-11 cycle has all to do with leap years. You can see that in the 2nd figure above.

The 5-year gap comes about when we have had TWO leap years, e.g., 1996 & 2000. In each case we LEAPT over a day (which is why we call it a Leap Year, i.e., because we leap over a day, in the calendar). Because of the two leap years, the gap was only 5-days. Then, between 2000 and 2006 there was only ONE leap year. So we only leapt over one-day. The gap was thus 6.

Next year, i.e., 2021, it falls on a Saturday — BUT the Friday, Christmas Eve will be a holiday.

Note how Leap Years break
up the sequence — hence the
name ‘Leap’, since days leap ahead.



Last time we had Christmas, i.e., December 25th, on a Wednesday was in 2013 — 6-years ago.

2017 Christmas On A Monday — First Time In 11-Years; Last In 2006.

Leap Years marked in grey.



Last time we had Christmas, i.e., December 25th, on a Monday was in 2006 — 11-years ago.

That is unusual, but not extraordinary. We get a 11-year gap, every 4th time around. The cycle as to when the same date falls on a given day (e.g., Monday) goes in 1 6-5-6-11 cycle. You can see that in the last image above — as to when Christmas has fallen on a Monday. So, it was 1989, 1995, 2000, 2006 …. and then 2017.

This 6-5-6-11 cycle has all to do with leap years. You can see that in the 2nd figure above.

After 1995 it was but 5-years because we had TWO leap years, i.e., 1996 & 2000. In each case we LEAPT over a day (which is why we call it a Leap Year, i.e., because we leap over a day, in the calendar). Because of the two leap years, the gap was only 5-days. Then, between 2000 and 2006 there was only ONE leap year. So we only leapt over one-day. The gap was thus 6.

Now look at what happened in 2012, which was a leap year. That should have been the Monday, but we skipped over that. Hence, the 11-year gap. Neato. This 6-5-6-11 cycle is inescapable and applies to all calendar events, birthdays, holidays, whatever.

Some of you may claim “but, didn’t we have Christmas on a Monday last year (2016), in 2011 and in 2005?” NO, you didn’t! Christmas, on those years, fell on Sunday. So, Monday was made a holiday. Big difference. OK?
