God said, “Let there be lights in the expanse of the sky to separate day from night; they shall serve as signs for the set times—the days and the years; and they shall serve as lights in the expanse of the sky to shine upon the earth.” And it was so. God made the two great lights, the greater light to dominate the day and the lesser light to dominate the night, and the stars. And God set them in the expanse of the sky to shine upon the earth, to dominate the day and the night, and to separate light from darkness. And God saw that this was good. And there was evening and there was morning, a fourth day.
-- Genesis 1:14—19
Tradition holds that the sun was created at the spring equinox, the first hour of the night before the fourth day of Creation. Every 10,227 days – according to the Babylonian Talmud, tractate Berachot 59b – the sun returns to its position at Creation. As codified in the Shulchan Aruch and on the basis of intricate calculations reconciling the Jewish and Gregorian calendars, Birkat HaChammah, a prayer service marking this 28-year cycle, is conducted on a Wednesday in the month of Nissan, when the sun is about 90 degrees above the eastern horizon.
The year 5769 is such a year. The Blessing of the Sun takes place on April 8, 2009 (erev Pesach). It is interesting to note that the secular date was the same throughout the 20th century, and scholars have determined it will continue to be marked on this date throughout the current century.
In recognition of the stresses on the world's environment, many and varied Jewish organizations also are seeking to make this a singular occasion for raising our awareness and taking responsibility as caretakers of "the Earth and all that dwell therein."
