The idea
A birthday tells you how many years you have — a tidy, slightly abstract number. But you don’t live in years. You live in seconds, heartbeats and breaths, and those counters have been running without a single pause since the day you arrived. This instrument doesn’t just read them out: it lets you watch them run.
Press the button and your almanac comes alive — the seconds climbing, the heartbeats overtaking them, the odometer of your trips around the Sun creeping forward eight decimal places at a time. Nothing about you changes; the scale of what you are already doing simply becomes visible, second by second.
How it’s measured
The foundation is exact: we take your date of birth and count the precise seconds to this very moment, leap years included, and the day counter is that figure divided out by full days. From there, the live counters advance at well-documented average rates — a resting heart at 72 beats per minute (1.2 per second), breathing at 16 per minute, and about 15 blinks per waking minute spread across the day. “Trips around the Sun” uses the astronomical year of 365.2425 days, which is why you can watch its eighth decimal move.
Body figures are honest averages, not medical measurements — your true totals depend on your own heart and lungs. The rates, though, tick exactly as stated, from the millisecond you press the button.
Questions, answered
Are leap years counted?
Yes. The count is real date arithmetic between your birth date and this exact moment, so every leap day you have lived through is automatically included.
Does a shared link keep counting too?
It does — that’s the fun of it. A shared link stores only the inputs, and whoever opens it sees the counters recomputed to their “now” and still running. You are sharing a living reading, not a screenshot.
Is my birthday stored anywhere?
No. Everything is computed in your browser and nothing is sent to any server. If you share your result, the link itself carries the inputs you chose to include — that is all.
