How old is your favourite language?

We often forget for how long we’ve been writing code in specific languages. For example, I started using SAS in 1992 for the analysis of progeny trials, Python to control Fortran sampling simulations in 1997, and R for general statistics in 1998. Your favourite language could be fairly old:

Fortran: 66 years old
COBOL: 64 yo
Lisp: 63 yo
BASIC: 59 yo
C: 51 yo
SAS: 51 yo
SQL: 49 yo
MATLAB: 44 yo
C++: 38 yo
Python: 32 yo
R: 30 yo
Java: 28 yo
Ruby: 28 yo
Javascript: 27 yo
Clojure: 16 yo
Julia: 11 yo
Elixir: 11 years old
