Snow Day Calculator helps parents, students and teachers across the United States and Canada estimate the chance of school closures during winter weather.
Enter your ZIP code, Canadian postal code or city to get a location-based snow day prediction. The calculator analyzes local hourly weather forecasts, focusing on early morning conditions from 3 AM to 7 AM when snow and ice can affect school travel. It considers snowfall, freezing rain, black ice, wind and extreme cold, along with regional differences in school closure patterns.
Our goal is to make winter mornings easier to plan. Whether you are preparing the night before or checking conditions in the morning, Snow Day Calculator gives you a simple way to understand possible school closure risks.
Predictions are estimates, not official school announcements. Always check your local school district for confirmed closure updates.
