Chronorius
Today in History
Free · Designed for iPad. Not verified for macOS.
What happened on this day – events, births and deaths, with sources. Loaded days work offline. No ads.
Chronorius shows for every day what happened on that date: events, births, deaths and observances. The entries come mainly from Wikipedia and Wikidata, plus a few curated entries. For every detail you can see where it comes from.
TODAY
The day’s events in chronological order, split into events, births and deaths. A timeline on the edge jumps straight to a year. Filter by topic and world region.
DETAILS
For each entry: the sentence about what happened, the Wikipedia article in paragraphs, images with author and license, the place on a map and what happened before and after.
ORIGIN & SOURCES
Primary source, additional sources and retrieval date. Differing details from Wikipedia and Wikidata are shown, uncertain dates are marked. Errors can be reported or corrected on the device.
TOPIC GUIDES
Guided paths through Ancient Rome, the French Revolution, the Industrial Revolution, the Cold War and spaceflight.
PEOPLE
Life stages with education, offices, works and relationships, each with a source.

Version 1.0.3
• Origin & sources: every entry shows where its date, place, category and image come from. Differing details from Wikipedia and Wikidata are shown.
• Report an error: report wrong details by email or keep your own correction on the device.
• Uncertain dates are marked, for example Julian dates before 1582.
• Better matching: cards name the right article and the sentence about what happened. Categories fit better.
