NA Clean Time
Calculator

Clean time in Narcotics Anonymous refers to the continuous period of time a person has lived free from all mood-altering substances, including alcohol. It begins on your clean date — the last day you used — and accumulates continuously. Clean time is different from "sobriety" (an AA term) because it covers all drugs, not just alcohol. In NA, the phrase "clean" is used instead of "sober."

NA recognises the following milestones: 30 days (white keytag), 60 days (orange keytag), 90 days (red keytag), 6 months (blue keytag), 9 months (green keytag), 1 year (medallion) and then annually — 18 months, 2 years, 5 years, 10 years, 15 years, 20 years, 25 years. Each milestone is celebrated publicly at NA meetings, usually with a keytag or medallion and a moment for the member to share.

Simply enter your clean date — the date you last used any mood-altering substance — into the date picker above. Then click "Calculate My Clean Time." The calculator will show your exact clean time broken down into years, months, weeks and days. You'll also see all your NA milestones (which you've achieved and which are upcoming), plus a countdown to your next anniversary.

"Sobriety" is the term used primarily in Alcoholics Anonymous (AA) and generally refers to abstinence from alcohol specifically. "Clean time" is the Narcotics Anonymous (NA) equivalent and applies to abstinence from all mood-altering substances, including alcohol, prescription drugs used non-medically, and all illicit drugs. This calculator is designed for the NA definition of clean time.

No. This clean time calculator runs entirely within your browser. Your clean date is never transmitted to any server, never stored in any database and never shared with anyone — including Calcgator. The calculation happens locally on your device. Your recovery is your private journey.

In NA, clean time is continuous — if there is a use of any mood-altering substance, clean time restarts from that date. However, a relapse does not erase what you've learned or the recovery you've built. Many people in NA have multiple clean dates before finding sustained recovery. If this has happened to you, simply enter your new clean date. The most important day is today.

Yes! After calculating your result, you'll see a "Share on WhatsApp" button that creates a ready-to-send message with your clean time. You can also copy the link to this page. When you share via WhatsApp, only the message you send is shared — your clean date is not included unless you choose to include it.
