How to Use the Snow Day Calculator

Our Snow Day Calculator is a simple tool designed to help you estimate whether school might be closed due to winter weather. Here’s how it works:

Enter Your Zip or Postal Code

• Start by typing in your Zip Code (U.S.) or Postal Code (Canada).
• This field is mostly for context — in this demo version, it isn’t tied to live weather data.

Add the Expected Snowfall

• Enter the amount of snowfall in inches you think your area will receive.
• The higher the snowfall, the more likely schools are to shut down.
• Example: If you expect 6–8 inches, your chances are much higher than if you only expect 1–2 inches.

Include the Temperature

• Input the forecasted temperature (°F).
• Colder temperatures (below freezing at 32°F) make snow and ice stick longer, which increases the likelihood of school closures.
• Milder temperatures mean roads may clear faster, lowering your snow day chances.

Select Your School Type

• Choose between Public, Private, or Boarding school:
  
  • Public Schools: Usually more cautious with closures.
  • Private Schools: Often close a bit quicker.
  • Boarding Schools: Less likely to close since students live on campus.

Hit the “Calculate” Button

• Once you’ve filled everything out, click the purple Calculate button.
• The calculator will give you a percentage showing the chance of having a snow day.
• Example: “Snow Day Chance: 65%”

How Does It Work Behind the Scenes?

• The calculator employs a straightforward formula that considers snowfall, temperature, and school type.
• More snow = higher probability.
• Lower temperatures = higher probability.
• School type adjusts the numbers slightly up or down.
• The result is capped between 0% (no chance) and 100% (guaranteed snow day).

Important to Know

• This tool is meant for fun and rough estimation.
• It doesn’t pull real-time forecasts — so if you want accuracy, check your local weather app or news.
• Think of it as a playful way to guess whether you’ll get that surprise day off!
