Sobriety calculator

Enter your sobriety date and the calculator counts your sober time in total days and in years, months and days. It also lists the date of each milestone: 24 hours, 30, 60 and 90 days, 6 and 9 months, 1 year, 18 months, and every year after. It is free, there is no sign-up, and the date never leaves your device.

How is sober time counted?

Your sobriety date is the first full day you did not drink. On that date the count is 0 days, and it reaches 1 day the next day. The total is the number of calendar days from your sobriety date to today. Months and years follow the calendar, so a year is the same date a year later. When that date does not exist, the milestone falls on the last day of the month: a sobriety date of February 29 reaches 1 year on February 28.

What is an example?

A sobriety date of March 1, 2025 reaches 90 days on May 30, 2025, 6 months on September 1, 2025 and 1 year on March 1, 2026, which is 365 days.

Is my date saved?

No. The calculator runs entirely in your browser. The date you enter is not saved, not sent to us and not added to the page address, and it is gone when you close the page.

Coming up on 90 days? Track them with the 90 in 90 tracker, or find an AA meeting tonight.
