Owing to the population distribution of the Earth (fewer people live at the North Pole so after the June solstice once the Sun has slipped a bit further south toward the more populous equator), the different definitions of sunrise, sunset and twilight—civilian, nautical and astronomical and the underestimated size (half the globe) of the Pacific Ocean, on 8 July annually about ninety-nine percent of the people of Earth will be under the sun, experiencing daylight after a fashion at the same time. 
Despite the two hemisphere and the progression of the seasons, during the northern summer, this sunny side phenomenon can occur for a couple of minutes each day from mid-May through mid-July—charted out after some fact-checking on what seemed like an outrageous but somewhat true internet claim, and while it might be a bit more intriguing to have found it a singular instance on the calendar when only one percent of the world’s population was (temporary—Oceana and Baja California still get their daylight hours, just after the rest of the world’s dusk and dawn), it’s even more remarkable that it happens over a span of sixty days.
