The long summer days are fading as cities like Chicago, Boston, and Denver have experienced their last 8 p.m. sunset of 2025; they won't see another until 2026. Increasingly earlier sunsets mark this seasonal shift due to Earth's tilt and orbit. Since the summer solstice on June 20, days have been shortening, with the pace accelerating in August by 1-2 minutes daily. By August 31, daylight is over 60 minutes shorter than on August 1. Cities like Seattle lose up to 92 minutes of daylight, while Miami loses 40 minutes. This trend continues until the winter solstice on December 21. https://www.accuweather.com/en/space-news/goodbye-long-days-cities-that-have-already-had-last-8-pm-sunset-of-2025/1803384
