FAQs

How accurate is US Snow Day Calculator?

US Snow Day Calculator is designed to give a realistic estimate of snow day chances, not a perfect prediction. It looks at real forecast data, winter alerts, and school type to produce a probability. Weather and human decisions are both unpredictable, so no tool can be 100 percent accurate. Use the percentage as a planning guide and always confirm with official school announcements.

US Snow Day Calculator can help you plan and set expectations, but it should never be the only source you rely on. School closure decisions are made by local administrators who consider many factors, including roads, buses, staff, and safety. Always follow your school or district for final decisions.

Accuracy depends on how well a tool combines real weather data with realistic school decision patterns. US Snow Day Calculator focuses on three things: quality forecasts, transparent rules, and clear explanations. No calculator can guarantee a result, but our goal is to provide honest probabilities that match how many schools actually behave in winter weather.

US Snow Day Calculator takes your ZIP code and school type, then pulls forecast and alert data for that area. It looks at snowfall amounts, timing, ice and freezing rain risk, wind chill, and official winter alerts. Those inputs pass through a rule based model that produces a snow day probability and a simple explanation you can understand at a glance.

The calculator uses real weather forecast and alert data from trusted meteorological sources, combined with location information based on your ZIP code. It focuses on factors that matter most for school closures like overnight snow, morning road conditions, ice, extreme cold, and active winter storm warnings or advisories.

No account is required to use the calculator. The tool mainly uses your ZIP code and general technical data such as browser type for analytics and performance. For more details, you can review the Privacy Policy page on the site.
