Sobriety Calculator: How Many Days Sober Are You?

The calculator above gives you the number. This guide explains where it comes from: how to count from your sobriety date, why another site might say one day more, which milestones come next and what to do if you slip. It ends with where to find help, today if you need it.

How to calculate your days sober (day 0 or day 1?)

Your days sober are the full days since your sobriety date. Subtract your sobriety date from today's date and you have the count. With a sobriety date of March 14, 2026, you are 232 days sober on November 1, 2026. Counted the other way, with your sobriety date as day 1, that same Sunday is day 233.

Both ways are common. Many people in AA pick the first full day without a drink, so the evening of the last drink falls the day before. Your sponsor, group or counselor may have a preference, and that's worth following. Neither way is wrong.

Here's how the two numbers move, day by day:

That's why the calculator always shows both. The big number is your full days sober. Tick "Count my sobriety date as day 1" and the day number moves to the front instead. Nothing else changes.

Sobriety milestones: chips, keytags and what comes next

The milestones people mark most often are 24 hours, 30, 60 and 90 days, 6 months, 9 months, 1 year and then every year. Many AA groups hand out a chip or medallion at some of these moments. It's a custom, not a rule: every group decides for itself which milestones it marks and how.

In NA, people usually talk about clean time rather than sober time, and many groups give keytags for a similar series of milestones. Colors and designs vary by group and by who makes them, so ask your own group what to expect.

The calculator adds 7 days, 100 days, 18 months and 1,000 days, because people like to mark them too. Days are added as days. Months and years are added on the calendar, so 6 months after March 14 is September 14. For the page's example date, these are the milestones:

On November 1, 2026, the next one on that list is 9 months, 43 days away. The tool shows the same table for your own date, with each milestone marked as reached or with the days to go. Greatr is not affiliated with Alcoholics Anonymous or Narcotics Anonymous.

How we calculate your sobriety time (and why calculators disagree)

We subtract your sobriety date from today's date, in full calendar days, using the date on your own device. When two calculators disagree, they usually differ by exactly one day, for one of three reasons: they count the sobriety date as day 1, they use another time zone, or they treat a month as 30 days.

The formula, in one line:

days sober = today's date minus your sobriety date (full calendar days, your local time zone)

Two edge cases follow from counting on the calendar. A sobriety date on the 31st has its month milestones on the last day of shorter months: from January 31, 2026, 6 months falls on July 31, but 1 month is February 28. And a February 29 date has its anniversary on February 28 in other years. From February 29, 2024 to February 28, 2025 is 365 days and exactly 1 year.

The live clock starts at the time of your last drink or use, if you add it, and otherwise at 12:00 AM on your sobriety date. Your day count always starts at your sobriety date. So the clock can show a few more hours than days times 24, and that's expected. Daylight saving time can add or remove one hour on the clock, but never a day from the count.

Money not spent and time back are estimates from what you type in: what it cost per day (or per week divided by 7) times your days sober. At $20 a day, 232 days is $4,640. They're rough on purpose, so use them as a nudge, not a ledger.

Sobriety calculator vs sobriety counter app: which do you need?

A calculator gives you the number at one moment, for a meeting, a card or a quick check. A counter app keeps counting every day and is there when you open it. If you want the number now, a calculator is enough. If seeing it each morning helps you, you want something that keeps the count.

This tool does a bit of both, without an account. Switch to the live sober clock and it counts the days, hours, minutes and seconds while the page is open. Press "Copy link with my date" and your date goes into the page's address. Bookmark that link or add it to your home screen, and the count is waiting next time. Nothing is stored anywhere else.

If you pick a counter app, look for these:

• The core counter works without paying
• No account needed to see your count
• Your data stays on your device
• It works offline
• A reset that does not shame you
• Milestone reminders you can switch off

Be honest with yourself about what a counter is. It shows your time. It does not replace treatment, a sponsor or meetings. For a date that has nothing to do with recovery, like a move or a work anniversary, the days since calculator is the simpler tool.

What if you slip? Resetting your sobriety date

Many people choose a new sobriety date after a relapse, and many groups ask for that. But the days you already had stay real. You learned things in them that a new date does not erase. Whatever you decide about the number, what matters most is the next day.

Relapse is common, and it does not erase the recovery you have built. The National Institute on Drug Abuse estimates that 40 to 60 percent of people treated for a substance use disorder relapse, compared with 50 to 70 percent of people treated for high blood pressure or asthma. NIDA's point is that relapse is a signal to adjust treatment, as it would be for any chronic condition.

What helps in practice: talk to your sponsor, your group or whoever treats you, and do it soon. In this tool you simply enter the new date. There is nothing to undo and nobody sees it but you.

If the stress of work or caring for others is part of what pulls you back, the burnout quiz can help you name it.

What changes after 30, 90 and 365 days sober?

It varies more than most day-by-day charts admit, and good research on exact timelines is thin. What the evidence does support: the first days carry real medical risk for heavy drinkers, blood pressure tends to come down when heavy drinkers cut back, and the risk of relapse stays real past the first year.

Here is what we can say carefully at each milestone:

The blood pressure finding comes from a 2017 meta-analysis by Roerecke and colleagues of 36 trials with 2,865 participants. People who drank two drinks a day or fewer saw no clear drop from cutting back. Those who drank more than six drinks a day and cut their intake by about half saw their systolic blood pressure fall by about 5.5 mmHg and their diastolic by about 4.

This is general information, not medical advice. Your own body, history and medication matter. Your doctor can tell you which checkups make sense for you.

Build a daily routine that supports your recovery

A steady day helps many people in recovery: the same small things, in the same order, every morning and evening. Keep it short and easy to repeat. Two minutes of breathing after coffee and a call to your sponsor on the drive home count. A routine you keep on hard days beats a perfect one you skip.

In Greatr you build a morning routine, an evening routine or both, by stacking small habits in a fixed order: meditation, journaling, breathing, reading or a workout. You can add your own habits too, like "go to a meeting" or "call my sponsor." Greatr counts the days you show up for your routine. That streak is about the routine, not about your sobriety date.

Evenings are often the hardest part. If you lose them to your phone, check where your hours go with the screen time calculator, and see these good habits examples for small ones to stack. The Atomic Habits cheat sheet explains how to attach a new habit to one you already have.

Greatr is a routine app. It does not replace treatment, a sponsor or your group.

Where to get help

You don't have to do this alone, and you can get help today. In the US, SAMHSA's National Helpline is free, confidential and open 24/7, 365 days a year, in English and Spanish. It refers you to local treatment, support groups and community organizations.
