Mark your calendar for Judaism's once-in-28-year special event. Jewish calendar, Creation took place 5,769 years ago. Why recite this blessing now? Why only once every 28 years? And how can this blessing help us grow closer to God in our daily lives? The sun resets to its original starting point once every 28 years. In order to understand Birkat HaChama, a bit of astronomy is necessary. The Torah teaches that on the fourth day of creation -- that very first Wednesday of world history -- God created the sun (Genesis 1:16). A solar year is 365 1/4 days long -- i.e. 52 complete weeks, plus 1 1/4 days left over. That means each year, the sun returns to its starting point 1 1/4 days later in the week. The sun resets to its original starting point -- at the first hour of Wednesday morning -- only once every 28 years. (Do the math.)
