Just Launched: Snow Days Calculator – Predict School Closures with Weather Data

#productivity #weather #webdev #beginners

Ever woken up wondering: “Will school be closed today because of snow?”

I did — and that’s why I built the Snow Days Calculator.

This simple app estimates the chance of a snow day based on live weather data and historical snowfall records.

It works for users in the US, Canada, Europe, and Australia — and it's totally free.

🚀 What is Snow Days Calculator?

Snow Days Calculator is a lightweight tool and Chrome extension that helps students, parents, and educators check the likelihood of school closures due to snow.

No more manually checking forecasts or guessing.
