 Dear Sundial friends,
As Manolo Pizarro already wrote in this list, Spanish gnomonist Esteban 
Martínez has launched the idea to stablish the World Sundial Day.
You can find this initiative in his web page Reloj Andalusí - Página principal 
(relojandalusi.org)
Following,  there is a translation of the text supporting his proposal.
Reason ► Sundials have been the most common form used for measuring time by 
allcivilizations until the appearance of mechanical clocks, even coexisting 
with them. Sundialsrepresent the union of disciplines as disparate as 
Astronomy, Mathematics, Geography, etc.They have an undoubted didactic value in 
teaching astronomy to young people and as anobject present in public spaces, in 
places where people can better understand our relationshipwith the Sun. They 
bring together Science and Art, the greatest exponents of human Reasonand 
Creation
Claim ► They are differentiated and unique pieces of all the peoples of the 
Earth andtherefore need special legal protection. We promote its inventory 
globally and the creation of aunique figure that legally protects historical 
and modern sundials.
Why the establishment of a World Day ► With the celebration of World Sundial 
Day, weintend to raise awareness among citizens about the importance that 
sundials have had in allcultures, making information available to them in order 
to activate the political will andresources to address their protection as 
fundamental and differentiated elements of WorldHeritage
Proposed Date of Celebration ► We propose the celebration of World Sundial Day 
on theSpring Equinox, the first day of the year on which the shadow in sundials 
casts a straight lineon a plane. And it is on the first of the equinoxes 
because already in Roman times the month ofMarch was the month in which the 
year began. In this year 2024 the date is March 20.

Please share this project with friends, schools and groups of interest in this 
area.Regards to all
José C.Montes y Martha A Villegas from México.
