Most countdowns face forward — how many days until something. The other direction is just as useful. A days-since counter measures how long it's been since you started or stopped something: a habit, a job, a relationship, a quit date. The number gets bigger every day, and over time it becomes the kind of evidence that's hard to argue with. This page is about when that's helpful, when it isn't, and how to set one up that you'll still be using a year from now.
To create one, open the home page, name it (be specific — "Sober" or "Quit smoking" or "Daily walk streak"), pick the date you started, and toggle the direction to "Days Since." The counter goes up by one every midnight on your device.
What the count is good at
A days-since count does three things well:
- It makes invisible progress visible. The work of changing a habit is done in tiny daily increments that don't look like anything in the moment. The counter is what tiny increments look like in aggregate. At day 14 you have something to point at; at day 100 you have something to be proud of.
- It moves the goal post in a useful way. When the goal was "stop drinking" or "exercise more," the goal can feel both abstract and never-finished. "Don't break the streak today" is a smaller, immediate goal that maps directly onto the larger one.
- It dampens the urge to renegotiate. Big numbers feel costly to lose. At day 3 it's easy to think "I'll just have one." At day 130 the same thought has 130 days of momentum to overcome.
What the count is bad at
Knowing when to set the counter aside matters as much as knowing when to start one.
- It punishes restarts. If your goal is a long-term change (eating better, exercising more, drinking less), a single bad day shouldn't reset everything to zero — but a streak counter implies it does. For these goals, a counter that tracks "days you stuck to it this month" is healthier than a single all-or-nothing streak.
- It can become the goal. The point of being sober for 200 days is being sober, not the number 200. When the number starts mattering more than the underlying behaviour, the counter is leading you, not the other way around.
- It's not a substitute for help. For sobriety, recovery, and other serious changes, a counter is one tool among many. It works alongside professional support, peer groups, and people who care about you — never as a replacement for them.
What to count and what not to count
The best candidates for a days-since counter share three properties: a clear start date, a binary daily check (yes or no), and a goal where consistency matters more than intensity. Some examples that work:
- Days since I quit smoking
- Days since I started learning a language daily
- Days since my last social-media binge
- Days since I started a daily walk
- Days since I last skipped a planned workout
- Days since the start of a relationship or marriage anniversary tracker
- Days since starting a new job
- Days since adopting a pet
And some that don't work as cleanly:
- "Days since I felt better." Mood doesn't have a clean binary check. A more useful version is "days since I logged a check-in" — making the count about the practice, not the feeling.
- "Days since I lost weight." Weight fluctuates daily for reasons unrelated to behaviour. Count the behaviour ("days since I tracked my meals"), not the outcome.
- "Days since I last argued with X." Anything where another person's actions affect the streak gives them too much control over your sense of progress.
Two examples
Quit-smoking counter
Set the start date to the morning after the last cigarette. Name it "Quit." For the first three weeks the count itself is the reward — it goes up faster than any other metric of progress. After about a month, the day-to-day urgency fades; this is where many people delete the counter. Don't. The 100-day, 365-day, and 1,000-day milestones are the ones that compound. A five-year days-since count is the kind of evidence that no relapse can erase from history.
Daily-walk counter
This one is harder than it sounds, because a daily walk is the kind of thing that's easy to skip "just today." Set the start date to the first day you actually walked. If you miss a day, the question is whether to reset or not — and the honest answer depends on what you want the counter to teach you. If the lesson is "consistency is the goal," a single missed day should reset; the cost of resetting is what teaches the lesson. If the lesson is "more days walked than not," count cumulative days instead and accept that the streak isn't the right frame.
Decision criteria: streak or cumulative?
Two common framings exist and they're not interchangeable:
- Streak count. Days since the last "miss." Goes up by one every day you stick to the behaviour; resets to zero on a miss. Best for habits where one bad day is genuinely costly (sobriety, no-contact in some recovery contexts, anything where the absence is the point).
- Cumulative count. Total days you stuck to it. Goes up by one only on success days; misses don't reset it, they just don't add. Best for habits where the goal is "more often than not" rather than "every single day."
This site's days-since counter is a streak-style count. If your goal fits a cumulative model better, you can keep a manual count separately, or pair the streak with another tracker.
Common mistakes
- Starting too many at once. The first counter has the most attention. The fifth has almost none. Pick the one that matters most and start there.
- Resetting in shame. If you lapse, restart. The day-1 of a second attempt is statistically more likely to succeed than the day-1 of a first attempt.
- Refreshing the page hoping the number went up. It changes once a day, at midnight on your device. Watching it doesn't help.
- Treating the counter as the only metric. Sleep, diet, exercise, and the people around you matter more for almost any change than any tracking app.
- Hiding it. Counters work better when they're somewhere you'll see them daily.
When to retire the counter
At some point a habit becomes part of who you are, not something you're tracking. The counter has done its job when the answer to "would you go back?" is a flat no, regardless of the number. At that point the count becomes a quiet souvenir rather than a tool. It's fine to keep it around; it's also fine to delete it. The change is what mattered, not the digits on the screen.
If you're newer to using a counter, start with the math behind it in how to count the days between two dates. If you're tracking something tied to a future date as well — a sober milestone, a one-year anniversary — pair this with the create-a-countdown form so you can watch both directions at once.
