Sobriety date calculator

How your sober time is calculated

The day count is the number of calendar days between your start date and today. Your start date is day zero. The breakdown counts years, months, and days, accounting for different month lengths. Dates use your device’s local time zone; daylight-saving changes do not change the day count.

Your next milestone may be a set number of days or a calendar anniversary. A month is not always 30 days. You can enter any personal start date; the calculator does not choose a sobriety date for you.
