- You can also select only one fact item
- It would take 5 - 60 seconds to see the results
- The result may not be comprehensive. We look for major events with standardized date information
- If you do not find interesting time information, try more concrete individual items (Tower Bridge: Q83125) instead of abstract concepts (bridge: Q12280)
- There are still a lot of items without time information (U-boat: Q428661 ), although data is improved every day. Any volunteers can help to imoprove the data!

Only the higher layer (satellite image) is visible, when two layers are switched on with opacity 100% (higer layers have priority for visibility) — Timeline view showing the overlaps of items (persons)

Only the lower layer (topographic map) is visible, when all higher layers are switched off — Map view showing the distribution of locations related to each item

The satellite image is visible on top of topographic map, because the opacity of the higher layer (satellite image) is not 100% (30% transparent) — Network view showing the relationships of items (persons)

What is the Compare section (advanced mode)?

You can compare history of 4 fact items
Roughly speaking, the fact items are any entries found in Wikipedia

- AI information extraction: to automatically extract information from a website and add it to the results of the Compare search. Only the first part of the website will be used. It is an experiment and longer waiting time (1-2 minutes). The quality of result may vary due to complex data processing with AI (mistakes may occur). You get best results, if specifying a website with date information (e.g. timeline of a person, diary of an event etc). You can test with the following websites:
  - Beethoven timeline: https://www.classicfm.com/composers/beethoven/guides/beethovens-life-timeline-part-1/
  - History of USA: https://www.ducksters.com/geography/country/united_states_history_timeline.php
