Opening day arrived at the Epstein School (spread over Aug. 10, 11 and 14 for different age groups) and Atlanta Jewish Academy (Aug. 14) with great enthusiasm. For AJA, the 2017-18 school year marks the start of a new era of preschool through high school on one Sandy Springs campus. For both schools, the opening-week jitters and summer hangover had time to pass before a day celebrated with special events at day schools throughout the area: the total solar eclipse Monday, Aug. 21, which achieved about 97 percent totality in the Atlanta metro area.
