What is a sobriety date?
A sobriety date is the date someone personally considers the beginning of their sobriety or alcohol-free period. How a person defines that date can vary.
How is sober time calculated?
This calculator measures the time between your selected sobriety date and today's date. It provides totals in days, weeks and approximate hours, along with calendar-based years and months.
Is a month always 30 days?
No. Calendar months vary in length. For the total-month estimate, this calculator uses the calendar relationship between the start date and today's date rather than assuming every month contains exactly 30 days.
What if my sobriety began today?
The calculator will show zero completed days and recognize today as your starting date.
Is my sobriety date saved?
No. The calculation takes place in your browser and the date is not sent or stored by this calculator.
