In recovery the marking of time has a great significance. We mark time both for ourselves, but also to demonstrate to others that one can lead a productive drug and alcohol free life regardless of what happens. It is based upon the concept of a daily reprieve. Whether just out of a drug and alcohol rehab facility or with years of clean time, simply enter the last date of use and the sobriety calculator will figure out the years, months, weeks, days, minutes and seconds since you put down the drink or the drug. It is easy to use and read. Try it now.
