Sobriety Calculator
Enter your sober date to see how long you've been sober: total days, years, months and days on the calendar, weeks and hours, plus your next milestone. Add the time of your last drink if you know it, or leave it blank to count from midnight. Your sober date counts as day 0, and each full day is added at the same time the next day, the way Sober44 counts. It's a counter, not medical advice.

Your sober date
Your first full day without a drink. If you know when you had your last drink, enter that date and add the time below.
Leave blank to count from midnight at the start of your sober date.
Planning a quit date? The alcohol taper schedule calculator gives you a daily drink target for each day until then. If you drink heavily every day, talk to a doctor before you stop (MedlinePlus).
Your sober date is day 0, and a full day is added at the same time the next day. This page runs in your browser; nothing is stored or sent.
The same time, broken down
You just reached 30 days.
Milestones are 1, 7, 30, 60, 90 and 180 days, then each yearly anniversary. Days count calendar dates and hours are real elapsed time, so around a clock change they can look an hour out of step.

How this sobriety calculator counts your time
This page is a counter, not medical advice. Your sober date is day 0, and a full day is added at the same time the next day: at midnight if you leave the time blank, or at the time you enter. If you quit at the start of today, you stay at 0 days until the same time tomorrow, when you reach 1 day.
Take a sober date of September 1, 2026, checked at noon on September 28, 2026. That’s 27 days, or 3 weeks and 6 days, and 660 hours. If you number your sober date as Day 1, it’s day 28.
The time field is optional. Blank means midnight at the start of your sober date. If you enter the time of your last drink, the count starts then, and each new day arrives when the clock passes that time.
Days use calendar dates, so time zones and clock changes don’t shift them. Hours use real elapsed time. From midnight on January 1, 2026 to noon on September 28, 2026 is 6,491 hours, not 6,492, in US time zones that observe daylight saving time, because clocks sprang forward on March 8. Days and hours are worked out separately, so around a clock change they can look an hour out of step.
The numbers update when you load the page or change the date or time. They don’t tick live, but Sober44 does, down to the second.
Years, months and days: why the calendar and the day count differ
Total days is one steady count. Years, months and days follow the calendar, where months run from 28 to 31 days, so the two don’t line up neatly. Here’s how a few sober dates look at noon on September 28, 2026:
| Sober date | Total days | Years, months, days | Weeks and days |
|---|---|---|---|
| Sep 1, 2026 | 27 | 0 y, 0 m, 27 d | 3 w, 6 d |
| Jun 30, 2026 | 90 | 0 y, 2 m, 29 d | 12 w, 6 d |
| Mar 31, 2026 | 181 | 0 y, 5 m, 28 d | 25 w, 6 d |
| Jan 31, 2026 | 240 | 0 y, 7 m, 28 d | 34 w, 2 d |
| Sep 28, 2025 | 365 | 1 y, 0 m, 0 d | 52 w, 1 d |
| Feb 29, 2024 | 942 | 2 y, 6 m, 30 d | 134 w, 4 d |
The calculator counts whole calendar months from your sober date without going past today, then counts the days left over. When your sober date’s day number doesn’t exist in a month, it uses that month’s last day. From January 31, one month lands on February 28 (February 29 in a leap year), and March 1 is 1 month and 1 day. Each month is counted from the original date, not step by step, so two months after January 31 is March 31. A February 29 sober date has its anniversaries on February 28 in common years and on February 29 in leap years.
That’s also why 90 days isn’t 3 months and 180 days isn’t 6 months. A June 30 sober date reaches 90 days on September 28, which is 2 months and 29 days. The next-milestone line uses 1, 7, 30, 60, 90 and 180 days, then each yearly anniversary on the calendar date, so a 1-year mark can be day 366 when a February 29 falls in between.
Choosing your sober date
There are two common ways to set it. As Recovery.com puts it, “For some people, this is the last day they used alcohol or other drugs. For others, it’s the first full day after they stopped.” Both work here. For the first full day, enter that date and leave the time blank. For the last drink, enter its date and roughly when it was. Whichever you pick, keep it, so your count means the same thing from one day to the next.
After a slip, enter the start of your current stretch. What you do with your date is your call. Many AA members take a new date after any drink as a group custom, and SMART Recovery treats a slip as something to learn from. Our guide covers what to do with your sober date after a relapse in more detail. Slips are common: NIDA puts relapse rates for substance use disorders at 40% to 60%, similar to high blood pressure and asthma, and says “Relapse doesn’t mean treatment has failed.”
If your quit date is still ahead, the calculator shows how many days away it is and keeps the numbers at 0 until then. To plan the days before it, the alcohol taper schedule calculator gives you a daily drink target for each one.
If you drink heavily every day, talk to a doctor before you stop. MedlinePlus says you may be at risk for alcohol withdrawal if you stop suddenly, and may need medical care while you stop. Free, confidential help is available 24/7 from SAMHSA’s National Helpline at 1-800-662-4357.
Watch your count tick in Sober44
Sober44 keeps the same kind of count on your phone, and it updates live. It runs from the moment you quit and shows your days above a clock of hours, minutes and seconds, so each full day arrives at the same time you stopped.
Your sober time runs from your quit date or your latest “I drank” check-in, whichever is later. You can log cravings, and they never reset the count. If your quit date is still ahead, the app shows a countdown with a straight-line taper and a daily drink target instead.
It also keeps streaks, a history of your runs and milestone notifications, which are there for motivation, not medical advice. There’s no account, and your data stays on your phone. The counter, streaks and quit plan are free.

Frequently Asked Questions
Common questions about sobriety calculator
How many days sober am I?
Subtract your sober date from today's date. From Tuesday, September 1, 2026 to Monday, September 28, 2026 is 27 days. That's 3 weeks and 6 days, or 660 hours by noon. The calculator counts completed days, so a new day is added each time the clock passes your quit time, or midnight if you leave the time blank.
Does the day I quit count as day one?
In this calculator your sober date is day 0. You complete your first full day at the same time the next day, which is how Sober44 counts too. Many people and groups call their sober date “Day 1” instead. If you count that way, add one: from September 1 to September 28 is 27 completed days, and September 28 is day 28. Neither way is wrong. Pick one and stay with it.
Should my sober date be the day of my last drink or the day after?
Either works, and both are common. Most people use their first full day without a drink and leave the time blank, so the count starts at midnight. If you know roughly when your last drink was, enter that date and time instead, and the count starts at that moment. A last drink at 11 PM on August 31 and a sober date of September 1 both give 27 days on September 28. The time version has one more hour. If you're not sure of the time, just use the date.
How does the calculator work out years, months and days?
It counts whole calendar months from your sober date without going past today, then counts the days left over. If your sober date's day number doesn't exist in a month, it uses that month's last day. So January 31 plus one month is February 28, and March 1 is 1 month and 1 day. A February 29 sober date has its anniversary on February 28 in years without a leap day. Months vary in length, so a June 30 sober date reaches 90 days on September 28, which is 2 months and 29 days, not 3 months.
Why isn't my hours total exactly days × 24?
Hours are real elapsed time, and clock changes add or remove an hour. Midnight on January 1, 2026 to noon on September 28, 2026 reads as 270 days and 12 hours, which would be 6,492 hours. In US time zones that observe daylight saving time it's 6,491, because clocks sprang forward on March 8. A stretch that crosses November 1 gains an hour back. Days are counted by calendar date, so clock changes never move your day count.
What if I drank after my sober date?
For your current stretch, enter the first full day after your most recent drink, or that drink's date and time. Whether to start a new date is your call, and in a group it's often a local custom. Some people keep their first date and track total sober days as well. Our guide on whether to reset your sober date after a relapse walks through the options. In Sober44, an “I drank” check-in restarts the counter, and logging a craving never does.
Can I use this for a quit date that's still ahead?
Yes. Pick a future date and the calculator shows how many days away it is. The numbers stay at 0 until then. To plan the days before it, the alcohol taper schedule calculator gives a daily drink target for each day. If you drink heavily every day, talk to a doctor before you stop. MedlinePlus says you may be at risk for withdrawal if you stop suddenly, and may need medical care while you stop.
Does Sober44 count sober time the same way?
Yes, apart from the hour around a clock change. Sober44 counts from the exact moment you quit and ticks every second, so your day count goes up at the same time each day. It counts from your quit date or your latest “I drank” check-in, whichever is later. Logging a craving never resets it. A future quit date shows a countdown and a step-down taper plan instead. The counter is free, needs no account, and your data stays on your phone. This page runs in your browser and doesn't store or send what you enter.
