The tool turns your opening hours into three formats: JSON‑LD structured data under Schema.org, understood by Google, Bing and Seznam; a clear HTML table for your website; and short text like Mon–Fri 8:00–18:00 for social media and profiles. It handles lunch breaks, closed days, holidays and one-off exceptions.
Runs entirely in your browser. Nothing is uploaded or stored.
From–to times, and for days with a lunch break, the afternoon block. Tick closed days.
For example closed on 24 December or shorter hours on 31 December.
JSON-LD into the page head; the table where people look for it, usually the footer or the Contact page.
Whenever your opening hours change, go through this list:
Holidays are worth adding ahead of time. People search “open today” mostly on holidays and weekends.

Both are useful. Your Google Maps profile is Google's main source, but structured data on your website helps Bing, Seznam and AI assistants, and confirms that the details match.
Enter 00:00 as the closing time and the generator converts it to 23:59, as Schema.org recommends. Opening that continues after midnight is entered on the next day from 00:00.
Search engines compare data from your website, Google profile, Firmy.cz and other directories. Differences reduce trust, and customers end up at closed doors.
Anywhere in the page HTML, usually the head. If you have more structured data about the business, combine it into one block; the JSON-LD generator helps.
