Spanish sundialist Esteban Martínez has launched the resolution to establish the World Sundial Day to occur each year on the Spring Equinox.  According to the petition circulated by Martinez,

They have an undoubted didactic value in teaching astronomy to young people and as an object present in public spaces, in places where people can better understand our relationship with the Sun.

"Why the establishment of a World Day  With the celebration of World Sundial Day, we intend to raise awareness among citizens about the importance that sundials have had in all cultures, making information available to them in order to activate the political will and resources to address their protection as fundamental and differentiated elements of World Heritage."
