Introduction
A year passes and, looking back, it feels weightless. Not painful. Not memorable. Just — not-there. It is a very specific complaint of adult life. There is a reason.
Why This Matters
Understanding subjective time as landmark-density rather than clock-density gives us a lever — novelty, ritual, and meaning — to make years feel like they happened.
The Science
Wittmann (2009), in Philosophical Transactions of the Royal Society B, synthesised the neuroscience of time perception, arguing that subjective duration depends on the density of encoded events, embodied signals, and attentional engagement — not on physical time passing. Wearden (2015), in Consciousness and Cognition, reviewed passage-of-time judgements and confirmed that time feels faster when routine dominates and slower when novelty and salience are high, with corresponding effects on retrospective sense of a period.
Current Research
Contemporary work is exploring how deliberate novelty and ritual practice affect the retrospective density of life periods, particularly in later life.
Practical Implications
For anyone: put more landmarks in your year — unfamiliar places, meaningful firsts, shared rituals — not to fill it but to give the nervous system something to encode.
Common Misconceptions
**"Time flies because I’m getting older."** Partly. Also because routine density dominates novelty density.
Key Takeaways
- Subjective duration depends on landmark density.
- Routine compresses years; novelty expands them.
- Landmarks are designable.
