We run a database that tracks end-of-life dates for 485 software products — every version, every release date, every day the security patches stop. Which means we're sitting on something nobody else has bothered to assemble: enough lifecycle data to answer a simple question with actual numbers.
How long does a software version actually live?
We measured every version in the dataset with both a firm release date and a firm end-of-life date — 7,144 versions across 463 products — and computed the span between them.
The headline: 18 months
