year, in which case it "leaps" a day. Hence "leap year".
Of course, you birthday has to be after
Dear All,
Jack Aubert is spot-on right in his explanation.
The Italian for "leap year" is "anno bisestile"
which is not far from the Latin. I assume that
any Italian will, around the age of six, ponder
the underlying meaning and quickly discover what
it is all about.
I'm sure there are more than two of us and my Latin is pretty minimal.
The leap year date is a double-six (in French it is called "bissextile").
It is a second sixth date. The "sixth" means six days before the March

Hello Jos,
The concept of a leap year is a purely human invention to make minor
adjustments to our calendar year as it slowly gets out of sync with the solar
year, and as far as I know there is no way for a sundial to 'know' about leap
years.
Thank you,

Dear sundial freaks,
