What is my sobriety date?
Use the date you choose to mark the start of your sobriety. Enter it above to see your days sober and upcoming milestones. The calculator cannot determine that starting date for you.
How many days have I been sober?
Enter your sobriety date to count the calendar days through today. Your starting date is day zero. The next day is day one.
When is my next sobriety milestone?
The calculator marks 1 day, 1 week, 30, 60, and 90 days, 6 months, and each yearly anniversary. Month and year milestones follow the calendar.
What happens with leap years and short months?
We include leap days in your total. A February 29 anniversary falls on February 28 in a non-leap year. If a month does not have the original day, we use its last day.
Can I save or share my milestone card?
Yes. Save a free PNG image or use Share card on a supported device. You choose where it goes. A name is optional, and the card does not include your start date. Review it before sharing.
Is my information private?
Yes. No signup is needed. Your date and name stay on your device and are not sent to analytics. Reloading clears them. Sharing a card is your choice.
What if I’m starting again?
Choose a new date whenever you need to. A number does not measure your worth or erase your progress.
