The definition isn't that long. The definition is usually something like 1 year at the state level. But then the rules allow large chunks of time to be excluded from that 1 year requirement, like time waiting for a court doctor to declare someone competent, finding a witness, etc. In all my jury duty selections, the crime was committed 2-3 years before the trial commenced.
