Actually it turns out it isn't really every 7th one.  It is only the
years with the Dominical Letter A, whatever that is in the perpetual
calendar business.  If you are between the ages of 18 and 80, let's say,
there were only 6 dominical A years during that 62 year time frame, so
Mother's Day only occurred on May 14 averaging one year out of more than
10, not 1 of 7.  Very strange.

Not interesting to very many other people, I suppose, but 'curious' to
me.

Oh, I see now about the dominical letters in perpetual calendars.  There
are actually 14 different dominicals, not 7.  If a year starts on a
particular day of the week, that year might be a leap year or a regular
year.  But, there are less leap years, naturally, so the leap year
dominicals happen less frequently than the regular year dominicals.

I see.  I forgot about the leap year dominicals.  That adds 2 more
occurrences of dominical BA for the 18 to 80 year old born on Mother's
Day May 14 for a total of 8 instead of 6, so it is closer to one year of
9, not one of 10.  It is still kinda funky.  It is certainly not one in
7 as one might expect.
