2010 (MMX) was a common year starting on Friday of the Gregorian calendar, the 2010th year of the Common Era (CE) and Anno Domini (AD) designations, the 10th year of the 3rd millennium, the 10th year of the 21st century, and the 1st year of the 2010s decade.
2010 was designated as:
- International Year of Biodiversity
- International Year of Youth
- 2010 European Year for Combating Poverty and Social Exclusion
- International Year for the Rapprochement of Cultures
There is a debate among experts and the general public on how to pronounce specific years of the 21st century in English. The year 2010 is pronounced either "twenty-ten" or "two thousand [and] ten". 2010 was the first year to have a wide variation in pronunciation, as the years 2000 to 2009 were generally pronounced "two thousand (and) one, two, three, etc." as opposed to the less common "twenty-oh-_".
