Ohio Aviation and Aerospace History Education Week - Day 7:
^[oh-sp] The week of the seventeenth day of December is designated as "Ohio Aviation and Aerospace History Education Week" in honor of the anniversary of the Wright brothers' first flight. As used in this section, "the week of the seventeenth day of December" means the seven-day period beginning on a Sunday and ending on a Saturday that includes the seventeenth day of December.
Winter Solstice:
^[non] This year, the exact moment the winter solstice occurs is at 03:19 am (Central Time USA), which is the moment when the Earth is tilted the least toward the sun and receives the least sunlight. The winter solstice is the shortest day of the year in the Northern Hemisphere (the longest in the Southern Hemisphere), although is not, strictly speaking, the coldest day of the year. The winter solstice is the first day of astronomical winter and is also referred by many simply as "the first day of winter". The winter solstice does not fall on the same day every year, rather, it can occur at any time between the 20th and the 23rd day of December in the northern hemisphere.
