- Computed level: L2 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: everyday  ·  Arena: EmergenceLexicon

## Emergence
**Emerges from:** [pattern](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-pattern.regularity), [time](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-time.dimension), [regular](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-regular.frequency)

**Through:** pattern.regularity and time.dimension together allow regular.frequency to emerge, producing a sense of usual occurrence

**Novel properties:**
- temporal consistency
- predictable recurrence
- familiar pattern over time

## Examples
- The International Space Station orbits Earth every 90 minutes, maintaining this schedule for over 20 years. *(engineering)*
- Monarch butterflies migrate from Canada to central Mexico each autumn, a pattern observed for decades. *(biology)*
- The New York Stock Exchange opens at 9:30 a.m. Eastern Time on weekdays, a schedule kept since 1817. *(institutions)*
