Not having a fixed or regular time; occurring at irregular or unpredictable intervals.
From Greek 'a-' (without) + 'chronos' (time) + '-ous' (adjective suffix). An obscure term combining temporal negation with the adjective-forming suffix, rarely used outside specialized contexts.
Achronychous events are basically temporal chaos—they don't follow a schedule. A good example might be certain astronomical phenomena or biological events that happen unpredictably without a regular cycle.
