Read this before the arithmetic
Alcohol is one of the few drugs where stopping can be more dangerous than continuing. In someone who is physically dependent, withdrawal can produce tremor, sweating, severe insomnia, agitation and confusion, and in a minority of cases seizures or delirium tremens, which is a medical emergency and can be fatal without treatment. The risk is not evenly spread — it rises with daily drinking, with heavy drinking sustained over years, and with a history of previous withdrawal — but it is not something to assess by reading a web page.
If you drank daily, or heavily, or have had a bad experience stopping before, the first step is a doctor rather than a start date. Medically supervised withdrawal exists precisely because unaided stopping is not safe for everyone, and it is routine, not a last resort.
This page counts days and multiplies rates. It is not treatment, it is not monitoring, and it does not imply that stopping unaided is safe.
What the counts are built from
The day count treats the start date as day one; the "full days completed" line beneath it is the figure everything else uses. Drinks are converted from a weekly rate, so the totals move in fractions of a week rather than jumping on particular days.
The alcohol figure is standard drinks times grams per drink. The default of 14 grams is the US standard drink — a 12 oz beer at 5 percent, 5 oz of wine at 12 percent, or 1.5 oz of spirits at 40 percent all contain roughly that. Definitions differ internationally: 10 g is the standard unit in much of Europe and in Australia, the UK unit is 8 g, and Japan uses 20 g. The field is editable so the arithmetic matches whichever definition you are counting in.
The calorie line is ethanol only, at 7 kcal per gram, which is a fixed physical figure rather than an estimate. It deliberately excludes mixers, the residual sugar in wine and beer, and anything eaten alongside — so it is a floor, and for sweet drinks a low one.
The money side
Cost is entered per occasion rather than per drink, because most people can estimate what an evening cost more accurately than what each drink cost. Multiply the occasions by the weeks elapsed and you have the total. The annual figure extends the same rate across 52 weeks; like all such projections it assumes nothing else changes, which is why it is labelled as a rate rather than a forecast.
If you drank at home rather than out, the per-occasion figure works just as well — use what you spent per shopping trip divided by the occasions it covered.
Cutting down rather than stopping
The same arithmetic covers reduced drinking. Enter the difference between the old rate and the new one, and read the figures as what the reduction accounts for rather than as a total. The withdrawal warning above still applies to anyone reducing from a heavy daily intake, and reducing under medical guidance is the safer route in exactly the same cases.
For the calorie content of specific drinks rather than ethanol alone, there is the Alcohol Calories Calculator. For plain day counting between any two dates, the Date Calculator does that without any of the rest of this.
Questions people ask
Is it safe to stop drinking on my own?
For some people yes, for others no, and the difference matters. Physical dependence makes abrupt withdrawal genuinely dangerous — seizures and delirium tremens are the severe end and delirium tremens can be fatal untreated. Daily drinking, heavy sustained drinking, and any previous difficult withdrawal all raise the risk. A doctor can assess it in a short conversation and arrange supervised withdrawal or medication where it is needed. This page cannot make that assessment and does not try to.
What counts as one standard drink?
In the US, a drink containing about 14 grams of pure alcohol: 12 oz of beer at 5 percent, 5 oz of wine at 12 percent, or 1.5 oz of spirits at 40 percent. The definition is national, not universal — around 10 g in much of Europe and Australia, 8 g in the UK, 20 g in Japan. The grams-per-drink field lets you set whichever one you are counting in, and the alcohol and calorie lines follow it.
Why is the calorie figure lower than I expected?
Because it counts ethanol only, at 7 kcal per gram. Mixers, the sugar left in beer and wine, cream liqueurs and anything eaten alongside are all excluded, and for sweeter drinks those can exceed the alcohol calories on their own. Treat the number as the floor rather than the total.
Does the page track how my health is changing?
No. It counts days and multiplies the rate you gave it. Recovery timelines that assign changes to specific weeks circulate widely and none appear here, because what happens depends on how much and how long someone drank and on the rest of their health. Blood tests and a clinician are how that question gets answered.
