Has anyone an idea how to use a sundial for calculating if the current year is
a leap year? And, if not, how many years we are behind the next leap year?

Dear Jos,
You ask:

calculating if the current year is a leap
year?
Yes, been there, done that, got the T-shirt.
The Noon Mark on the new London Stock Exchange
in Paternoster Square more or less does what
you want but once you understand it, you

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,

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
calends (beginning of March). Therefore there is a second February 24 so to
avoid
