Planning an outdoor activity, like a wedding or family reunion?
Book it on a Saturday. Because the weather, and the air quality, will be better. NASA scientists say Saturdays are the sunniest days, thanks to air pollution. Because during the week, when most people commute, tiny particles from vehicle tailpipes and industrial smokestacks attract water droplets, forming rain and storms. On the weekends, there’s less pollution, meaning fewer storms, cleaner air, and sunnier days.
