Snow Day Calculator – A Smart Way to Predict School Closures


🧩 What is the Snow Day Calculator?

The Snow Day Calculator is an intuitive web-based tool designed to estimate the probability of a snow day (i.e., school closure) based on three primary weather conditions:

  • Snowfall (in inches)
  • Temperature (in Β°F)
  • Wind Speed (in mph)

This tool is especially useful for students, teachers, parents, and school administrators who want a quick forecast-based insight into the possibility of schools being closed due to severe weather conditions.


🎯 Purpose and Usefulness

Whether you’re a student hoping to sleep in or a parent planning for the next day, knowing the chance of a snow day ahead of time can help you save time, plan schedules, and reduce uncertainty.

Why use the Snow Day Calculator?

  • βœ… Time-Saving: Skip endless weather reportsβ€”get a simple percentage.
  • βœ… Helps in Planning: Allows parents and schools to make alternative arrangements in advance.
  • βœ… Educational: Understand how weather factors influence school closures.
  • βœ… Fun & Engaging: Kids and teens enjoy estimating their snow day chances.

βš™οΈ How the Calculator Works

The logic behind the calculator is based on a custom scoring system that considers the severity of snowfall, the danger level of cold temperatures, and the disruption caused by high wind speeds.

  • ❄️ Snowfall is multiplied by 2 because it’s the most significant indicator of a snow day.
  • 🌑️ Temperature contributes more if it falls below freezing (32Β°F), scaled by 1.5.
  • 🌬️ Wind Speed above 10 mph adds to the danger level, contributing to higher chances.

The final score is rounded and capped at 100% to present a clear probability.


πŸ–₯️ User Interface & Design

The tool is built using HTML, CSS, and JavaScript, with a focus on simplicity and responsiveness:

  • 🧼 Clean Layout: A neat container with input fields and a result display.
  • πŸ“± Mobile-Friendly: Works well on desktops, tablets, and smartphones.
  • πŸ§ͺ Interactive Inputs: Users can easily change values and instantly see results.
