Smoke-Free Days Counter
Pick the day of your last cigarette and this counts the days you have held since. Under three days it counts hours too, because that is how the first three days are actually counted. Your date rides in the link, so the link is your counter — bookmark it or send it to someone.
0 days and 10 hours since your last cigarette.
0 days smoke-free.
The day of your last cigarette. If you slipped, use the most recent one — the count is the distance from now, never a score.

Every rung is quoted from a published timeline: the World Health Organization, NHS Better Health and the National Cancer Institute. The WHO and the NHS give different times for carbon monoxide, so both are on the ladder rather than averaged into a figure neither of them publishes. The quit smoking timeline sets all of it out in full.

Why This Matters
A counter turns something invisible into something you can point at. Not smoking leaves no evidence — no photograph, no receipt, nothing to show for the afternoon you spent wanting one. A number that goes up every midnight is the evidence, and it is the only kind this habit produces.
The first three days are shown in hours on purpose. Day four to day forty are a matter of holding on; hour six of day one is a different problem, and rounding it down to "0 days" is the least useful thing a counter could do at exactly the moment it is being watched most closely.
Your date lives in the link, not in an account. That is a deliberate design: the address bar is the storage, so the counter survives on any device you paste it into, and there is nothing of yours on our side to lose or leak.
Next: what happens at each milestone, what those days have saved you, and where the nicotine went in the first 72 hours.
