How do you know what primary and secondary schools are closed on a certain day?

There's no single, global source to check school closures. The information is highly localized. To find out if a specific primary or secondary school is closed on a particular day, you need to check sources specific to that school and its location:

* School's Website: Most schools post closure announcements prominently on their website, often on a dedicated news or announcements page.

* School's Social Media: Many schools use social media (Facebook, Twitter, etc.) to communicate quickly about closures due to weather, emergencies, or other unforeseen circumstances.

* Local News: Local news websites and television stations often report on widespread school closures affecting a region due to weather or other major events.

* Local Government Websites: Some local government or education authority websites have a centralized list of school closures in their jurisdiction.

* Automated Phone Systems: Some schools use automated phone systems to notify parents and guardians of closures.

* Direct Contact: If you can't find the information online, calling the school directly is the most reliable method.

In short, your best approach is to start with the school's website and then expand your search to the other sources as needed. There's no single, universal database for this information.
