In contemporary history, the third millennium is a period of time that began on January 1, 2001, and will end on December 31, 3000, of the Gregorian calendar. This is the third period of one thousand years in the Anno Domini or Common Era.
As this millennium is currently in progress, its first two decades, the past 2000s and the current 2010s, are the subject of the historian's attention. The remaining part of the 21st century and longer-term trends are researched in futures studies. Currently, 12 years and 136 days of the third millennium have passed.
