How many years ago was 1900?
126 years, if you mean 1900 to 2026 as calendar years, which is how the question is usually meant. If you need it exactly, pick a date: 1 January 1900 was 46,286 days ago, 1 July 1900 was 46,105 days ago, 31 December 1900 was 45,922 days ago. Subtracting the years alone gives 126, but that quietly assumes a date, so the table below gives all three.
