The table lists the events Wikipedia records for one calendar date, today by default. Each row carries the year the event happened and the sentence Wikipedia publishes for it, ordered from the oldest entry to the most recent.
Two selectors above the table switch the date: choose a month and a day, press the button, and the page loads that day’s list. No account is needed and the address of the page stays the same.
English, Spanish, Portuguese, German and French lists come from the Wikimedia “On this day” feed for that language edition. The Japanese page reads the events section of the date article on ja.wikipedia.org, because the feed does not serve Japanese. VoriTools fetches the list, keeps a local copy for up to six hours and renders it; no entry is written by hand here.
Each language edition curates its own entries, so the lists differ: a day can hold a few rows in one language and dozens in another, and the French list is not a translation of the English one. The date shown is the date on the server (Asia/Shanghai), so visitors in other time zones may see the next or the previous day for a few hours.
Wikipedia’s selection is a starting point, not a citation. Dates before the Gregorian reform are usually given in the calendar that was in use at the time, and the same event can be filed under different years in different editions. A missing entry means the editors of that edition did not list it, not that nothing happened.
The wording is quoted, not rewritten: only markers such as “(in English)” that link to another language version are removed. Treat a row as a pointer to the article and check anything that matters against a primary source.
Wikipedia text is published under a Creative Commons Attribution-ShareAlike licence, and the exact version differs per language edition. Reusing a sentence means keeping the attribution and a link to the article it came from; the source line under the table is the attribution this page provides.
The rest of the page — the selectors, the year column and the ordering — is VoriTools’ own work. The list is ordinary HTML rendered on the server, so it works with JavaScript disabled and can be saved or printed with the browser.
