Vadillo https://relojesdesol.info P.D.: The WSD petition text in english: Reason ► Sundials have been the most common form used for measuring time by all civilizations until the appearance of mechanical clocks, even coexisting with them. Sundials represent 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 an object present in public spaces, in places where people can better understand our relationship with the Sun. They bring together Science and Art, the greatest exponents of human Reason and Creation Claim ► They are differentiated and unique pieces of all the peoples of the Earth and therefore need special legal protection. We promote its inventory globally and the creation of a unique figure that legally protects historical and modern sundials. 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. Proposed date of celebration ► We propose the celebration of World Sundial Day on the March Equinox, the day of the year on which the shadow in sundials casts a straight line on a plane and the day has a duration approximately equal to the one at night In astronomy it's the Aries point, the origin of right ascension with the Sun in the plane of the Earth's equator. Already in Roman times, the month of March was the month in which the year began. Note: This petition has arisen from the website "Reloj Andalusí" (www.relojandalusi.org <http://www.relojandalusi.org>) coordinated by Esteban Martínez Almirón, but has the support of numerous gnomonic associations, fans and web pages or blogs related to sundials and astronomy.
