Question five, Which Iranian celebration marks the year's longest night with gatherings featuring pomegranates and watermelon, readings of the poet Hafez, and a vigil passed midnight to greet the return of light. We'll be right back with these answers after this break. Welcome back.

2:03 Question one. What causes the winter Solstice's shortest day? Answer Earth's axial tilt. Earth is tilted about twenty three point five degrees, so in December, the northern hemisphere leans away from the Sun, shortening daylight. Earth's sun distance plays little role. In fact, Earth is near perihelion, closest to the Sun in early January. Question two, which Irish monument lights up at winter solstice sunrise? Answer? New Grange. New Grange, a passage tomb in County Meath, predates Stonehenge and the Egyptian Pyramids. Its precise solstice alignment shows sophisticated prehistoric astronomy and ritual attention to the return of light. Question three, what sweet is eaten at dung to symbolize reunion? Answer Tang Yuan tangyuan are round glutinous rice balls served in a light syrup.

2:52 Their name and shape of oak, unity and togetherness. In northern China, some families eat dumplings instead, but the theme of warmth and renewal is shared. What effect explains why the earliest sunset isn't on the solstice? Answer? The equation of time. Because the apparent solar day length varies over the year, solar noon drifts relative to our clocks. This equation of time offset separates the dates of earliest sunset and latest sunrise from the solstice itself. Question five. What is Iran's longest night celebration called answer? Yalda night Shabi Yalda Rooted in ancient Persian traditions. Yalda falls around December twentieth twenty one, the last night of the month Asar. It symbolizes light's victory over darkness as days begin to lengthen after the solstice. That concludes today's five daily trivia questions.
