Monday
Monday demonstrates absolute calendrical certainty, arriving every seven days with the reliability of a particularly unwelcome relative who has memorised your schedule. Ancient civilisations structured entire societies around this weekly phenomenon, with the Babylonians first codifying the seven-day week some four thousand years ago—inadvertently guaranteeing millennia of future suffering. Modern humans can predict Monday's arrival to the precise millisecond, yet this foreknowledge provides remarkably little comfort. Indeed, studies suggest that awareness of Monday's approach actually amplifies dread, with Sunday evenings showing measurable increases in cortisol levels across working populations. The phenomenon known as the 'Sunday Scaries' represents humanity's collective anticipatory anxiety, a psychological weather system of its own making.
Hurricane
Hurricanes, despite considerable advances in meteorological science, maintain an element of chaotic unpredictability that Monday cannot match. Whilst modern forecasting can identify potential storm formation and likely trajectories, hurricanes retain the capacity for sudden intensification, unexpected course changes, and general atmospheric misbehaviour. The Saffir-Simpson scale categorises these storms from one to five, yet any hurricane veteran will confirm that categories provide mere guidelines rather than guarantees. Hurricane paths resemble the wandering route of a particularly indecisive tourist, veering this way and that with little regard for human planning. This unpredictability, paradoxically, may generate less sustained dread than Monday's certainty—one cannot spend every day anxiously awaiting what might never arrive.
