Sobriety milestone calculator

Enter the date their sobriety began to see how far they’ve come and which milestones are coming up. Everything is calculated on your device.

This date stays on your device. It isn’t sent to us, saved, or added to the web address.

Why the dates matter

Early milestones

30, 60, and 90 days are often the hardest earned. A short note can mean a lot.

Months and years

Anniversaries are the moments most people mark. We use the same day of the month, adjusted for short months and leap years.

Round numbers

Day 100, 500, and 1,000 are worth noticing too, and easy to miss without a reminder.

Calculator questions

How do you count months and years?

An anniversary falls on the same day of the month as the start date. If that day doesn’t exist, such as February 29 in a non-leap year, we use the last day of that month.

Do you store the date I enter?

No. The calculation runs in your browser. Nothing is sent to our servers or put in the page address.
