In short
This sobriety calculator counts completed midnights in your time zone. The day you quit is day 0, and the number on the card is how many full days have passed since then.
How the days are counted
This sober time calculator uses completed calendar days in your time zone. The day you quit is day 0. At each local midnight the count goes up by one. If you quit this morning you’ll see 0 days, and a clock that is already moving.
Add a time if you want hours and minutes from that moment. Leave it blank and the clock starts at midnight. A daylight-saving night can be 23 or 25 hours; it still counts as one day. Leap day is included. A 29 February quit date has its yearly anniversary on 28 February when the year doesn’t have that date.
The date is saved in this browser only, so the next visit doesn’t start from a blank form. It is also put in the link, which is how sharing works. We don’t have accounts, and this site doesn’t use tracking cookies. Outpost, our iPhone app, counts a start date of today as day one. The two numbers differ by a day on purpose.
Questions
Is today day 0 or day 1?
Day 0. The headline is completed days: how long it has already been. A quit date of today stays at 0 until the next local midnight, then it becomes 1. Outpost on iPhone counts a start date of today as day one, so the app and this page differ by a day.
What if I don’t know the time?
Leave it blank. The clock then starts at midnight at the beginning of the date you chose. Add a time only if you want hours and minutes from a specific moment.
How do the milestones work?
Day marks such as 7, 30, 60, 90, 180 and 365 are completed calendar days, reached at midnight. 24 hours is exact elapsed time, so it can fall at a different clock time than the next midnight. “1 year” is the anniversary of the calendar date, which is 366 days later when a leap day sits in between.
What about leap years and clock changes?
29 February is counted. In a year without that date, the yearly anniversary lands on 28 February. Daylight saving can make one calendar day 23 or 25 hours long. The day count still moves at midnight. Hours follow the actual time that passed.
Can I use this as an AA sobriety calculator?
Yes, as a counter. Enter the date you count as the start of this stretch — many people in mutual-support groups use their sobriety date — and read 30, 60, 90 days and the yearly anniversary. Groups differ on chips and on which date to use. This page is not affiliated with Alcoholics Anonymous, and it isn’t a record of anyone’s program.
How do I find the date I’ll hit 100 days?
Set your quit date, then use “What date will I hit?”. One hundred days means 100 completed days, so the date is your quit date plus 100 calendar days. If you haven’t set a date, it counts forward from today.
Is my date stored anywhere?
Only in this browser, in localStorage, so you don’t have to type it again. The calculation happens on your device. There is no account and no tracking cookie. The address bar includes the date so a link can reproduce the count — anyone you send that link to can see the date.
How do you estimate money and drinks?
You enter what a typical week cost, or how many drinks it held. That weekly figure is spread evenly across the exact time since your quit date (168-hour weeks, not calendar weeks). It is an estimate you can change. It isn’t advice about money or health.
Is this medical advice?
No. It’s a calendar. If you’re unsure whether stopping drinking is safe for you, talk to a doctor.
