Fun Fact
Some regions with frequent snowfall are less likely to declare snow days with 20 cm of snow than warmer regions are with just 5 cm, due to infrastructure and preparedness.

Snow day predictions became popular alongside early weather forums and school district hotlines in the late 1990s. Modern online snow day calculators evolved as lightweight, heuristic-based tools meant for fun, planning, and expectation-setting rather than official forecasting.
