What this calculator does
This calculator counts the exact time you've been sober from a chosen start date, broken into years, months, and days, plus total days. It also flags your next milestone — 30, 60, 90, or 180 days, or each yearly anniversary — and how far away it is.
Worked example
A sobriety date of January 15, 2026, checked on September 2, 2026, shows230 days sober (7 months, 18 days), with the 1-year milestone 135 days away.
Common mistakes
- Counting the sobriety date itself as day one twice. The day count starts from your chosen date, so "day 1" is the day after, not the sobriety date itself.
- Forgetting leap years in long-term counts. Multi-year sobriety counts include any leap days that occurred in between, which a simple 365-day-per-year estimate would miss.
- Resetting the date unnecessarily. If you're tracking multiple attempts, keep using your most recent continuous sobriety date for an accurate current streak.
