The midpoint of summer, officially on August 7, 2023, marks the halfway point through the season, with daylight gradually decreasing since the June 21 Summer Solstice. At this juncture, the Sun's direct rays move southward, leading to earlier evening darkness. Summer, spanning from the Sun's 90 to 180 degrees of longitude, reaches its midpoint at 135 degrees longitude, aligning with August 7 in 2023. A traditional midpoint, Lammas Day, falls on August 1 and signifies a harvest festival, originating from Old English "loaf-mass." This date has shifted over time due to calendar adjustments. Notably, the true midpoint between the June solstice and September equinox for 2022 occurred on August 7. The decline in daylight becomes more pronounced in the latter part of summer, as the Sun's path and hours of sunlight diminish. With autumn's onset on September 23, daylight dwindles significantly, offering about 1 hour and 54 minutes less light in Philadelphia since August 7. This transition prompts seizing the remaining summer moments before colder temperatures and shorter days prevail.
