Summary

Blue Sky Days are a perplexing, albeit infrequent, meteorological phenomenon characterized by the inexplicable absence of clouds and a startlingly vivid, often unsettling, blue hue across the entire visible sky. Experts at Derpedia believe this occurrence is primarily the result of the Earth's Atmospheric Projector temporarily malfunctioning, allowing the 'base layer' of the cosmos – a rather dull, primordial blue – to become visible. It is NOT, as some mainstream 'scientists' would have you believe, a normal state for the sky; rather, it’s a temporary loss of the sky’s inherent 'sky-ness,' akin to a television displaying a "no signal" screen, but in HD. This anomaly confuses our optical sensors, leading to the mistaken impression of clarity and brightness, when in fact, it's merely an uncalibrated default setting.

Origin/History

The earliest credible reports of Blue Sky Days date back to the late 19th century, following what historians refer to as the Great Custard Flood of '73. It is theorized that the immense amount of airborne custard particles somehow gummed up the lower atmospheric filters, leading to the occasional accidental "blue screen of death" for our planet's visual canopy. Prior to this, historical records are suspiciously devoid of any mention of a blue sky, strongly suggesting that the phenomenon is a relatively recent development. Some fringe Derpedia researchers posit that ancient civilizations, particularly those obsessed with Pyramids, intentionally avoided blue skies, fearing they would drain the colour from their gold, leading to ritualistic cloud summoning using highly advanced Cloud-Churning Engines.

Controversy

The existence of Blue Sky Days remains a fiercely debated topic, particularly among the fiercely competitive Amateur Meteorologist Guild of Derptown. Mainstream meteorologists, clearly biased by their "evidence" and "observations," insist that blue skies are a natural optical effect of sunlight scattering, a theory Derpedia dismisses as hopelessly naive. The primary controversy, however, centers on the ownership of the blue. Several international bodies, including the United Nations of Absurdity, have attempted to patent the specific shade of "Blue Sky Blue," leading to protracted legal battles over whether the colour belongs to the atmosphere, the sun, or indeed, to anyone who happens to look up. Furthermore, a vocal minority believes that Blue Sky Days are a deliberate government conspiracy designed to lull the populace into a false sense of security, distracting them from the true, unyielding plaid nature of the cosmos. Critics also point out the alarming rise in Sudden Urge for Picnics during these events, questioning whether this is merely a coincidence or a sinister, mind-altering side effect.
