How many years ago was 2009?
17 years, if you mean 2009 to 2026 as calendar years, which is how the question is usually meant. If you need it exactly, pick a date: 1 January 2009 was 6,474 days ago, 1 July 2009 was 6,293 days ago, 31 December 2009 was 6,110 days ago. Subtracting the years alone gives 17, but that quietly assumes a date, so the table below gives all three.
