20042005

20042005 is a concatenated form used to denote the time span that covers parts of two consecutive calendar years, commonly written with a dash as 2004–2005. It serves as an identifier for periods that cross New Year’s Day and appears in various administrative and archival contexts. The label is frequently seen in academic calendars, fiscal years, and sports seasons, as well as in data records and file naming where a two-year range is needed.

In education, the 2004–2005 academic year typically begins in late 2004 and ends in mid-2005, with exact dates varying by country and institution. In government and business, a 2004–2005 fiscal year runs from a defined start month in 2004 to the same month in 2005; for example, the United States federal government used October 1, 2004 to September 30, 2005 for its FY2005. In sports, many leagues name seasons as 2004–05 to reflect competition spanning two calendar years, such as professional basketball and European football leagues.

Notable events associated with this period include the 2004 Indian Ocean earthquake and tsunami, which occurred in December 2004 and had widespread global impact, and the Kyoto Protocol entering into force on February 16, 2005. The span also encompasses ongoing political, economic, and cultural developments around the world in the mid-2000s, including various legislative actions, natural disasters, and international negotiations that shaped policy and discourse during those years.
