Event listings come from developers.events (the developers-conferences-agenda project and its contributors), licensed CC BY-NC 4.0, and from confs.tech (conference-data, MIT License). We merge them, filter out closed or unusable CFPs, and correct some dates, places and deadlines from each organizer's own page, so what you see is modified from the originals. More listings come from CallingAllPapers, which gathers them from several of these sources and Sessionize. Each event links to the organizer's own CFP page; only a short excerpt of that page is shown here.
Place coordinates come from OpenStreetMap data via Nominatim, © OpenStreetMap contributors (ODbL). Map tiles by OpenFreeMap. Drive times and flight times are estimates. No warranty: check the organizer's page before you submit.
