(WJW) – Winter weather is here again.

The key time period is through Sunday, with some areas still under a Winter Storm Watch.

Some may be wondering if school will be out.

Here’s a tool to help find out if your school district will get a day off.

Check out the Snow Day Calculator.

An MIT student who works with the National Weather Service designed it. All you need is your zip code.
