Finding Ourselves in Space and Time. Our ancestors’ understanding of what are – solstice, equinox and (yes) sunset was turned upside down pretty recently by Copernicus, Kepler, Galileo, and Newton. We forget how radical a change it was. We will get to see how frightening it was to be the first person to see the world differently. And of course we will watch the “sun set” over our equinox markers and feel where we are in the annual cycle.

Chávez / Huerta Commemoration

puede

In 2015 we added Dolores Huerta to the Commemorative Period, which extends from March 20th (the traditional beginning of the planting season) through the birthday of César Chávez (March 31st), the birthday of Dolores Huerta (April 10th), and then on the April 23rd, the anniversary of the passing of Chávez.

Welcome / Bienvenidos

The Solar Calendar – Tribute to César Chávez & Dolores Huerta is developing a comprehensive urban solar/lunar calendar at Chávez Park in Berkeley, California. The project will draw from design concepts in art, astronomy and architecture found at numerous ancient sky observatory sites around the world to inform the final design. The project seeks to:

• Promote an understanding of the Rhythm of the Seasons

• Honor the work, life and values of César E. Chávez & Dolores Huerta

• Provide an outdoor classroom to study science, math & culture

• Create a space for reflection in the midst of a busy urban environment
