Snow Day Calculator
Predict the likelihood of school closures based on current weather conditions and your school district’s policies

How Snow Days Are Determined
Temperature
Extreme cold (below 0°F) significantly increases snow day chances as buses may not start and walking becomes dangerous.
Snow & Ice
Accumulation of 6+ inches of snow or any significant ice accumulation makes roads impassable for buses.
Road Conditions
Rural districts often cancel with less snow due to slower road clearing, while urban districts have better resources.
Safety Factors
Districts consider wind chill, visibility, and timing of the storm when making closure decisions.
Every winter, students, parents, and teachers eagerly watch weather forecasts, hoping for that magical announcement: “School is closed due to inclement weather.” The anticipation of a snow day creates excitement across communities in colder climates. But how accurate are these predictions? Enter the snow day calculator – a tool that combines meteorology, statistics, and local knowledge to predict the likelihood of school closures.
In this comprehensive guide, we’ll explore how snow day calculators work, the key factors they consider, and why they’ve become an essential winter planning tool for millions of families.
What is a Snow Day Calculator?
A snow day calculator is a specialized tool designed to predict the probability of school cancellations due to winter weather conditions. By analyzing current and forecasted weather data along with local district policies, these calculators provide percentage-based estimates of school closures.
The concept gained popularity in the early 2010s when a high school student in New York created an algorithm that correctly predicted snow days with over 85% accuracy. Today, sophisticated snow day calculators consider multiple variables to deliver increasingly accurate predictions.
