2020
year
2020 (MMXX) was a leap year starting on Wednesday of the Gregorian calendar, the 2020th year of the Common Era (CE) and Anno Domini (AD) designations, the 20th year of the 3rd millennium and the 21st century, and the 1st year of the 2020s decade.
In 2020, the COVID-19 pandemic led to a global social, societal and economic disruption, mass cancellations and postponements of events, worldwide lockdowns, and the largest economic recession since the Great Depression in the 1930s. Geospatial World also called 2020 "the worst year in terms of climate change" in part due to major climate disasters worldwide, including major bushfires in Australia and the western United States, as well as extreme tropical cyclone activity affecting large parts of North America. A United Nations progress report published in December 2020 indicated that none of the international Sustainable Development Goals for 2020 were achieved.
The year also saw the rise of social protests and activism amidst the ongoing pandemic. The murder of George Floyd was widely condemned and lead to worldwide protests and unrest that lasted until 2023. In addition, elections commenced in numerous nations in 2020. Most notably, the 2020 U.S. presidential election where Democrat and eventual 46th president Joe Biden won against incumbent Republican Donald Trump. Trump refused to concede the presidency, leading directly into an attack on the US Capitol early the following year.
Time magazine used its sixth ever X cover to declare 2020 "the worst year ever," although the cover article itself did not go as far, instead saying, "There have been worse years in U.S. history, and certainly worse years in world history, but most of us alive today have seen nothing like this one."
Health
The outbreak of COVID-19 began in Wuhan, China, in December 2019.
Begin with the source’s own compact description: “2020” is year. The dossier treats that line as a proposition to test through year, not as a finished interpretation.
Why this record matters
The phrase “year” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 25, 2026. The linked authority identifier is Q25337. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2020, 2023 and 2019.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
