Sobriety Calculator

This tool counts the time between a date you enter and today, or another date you choose. It returns the total in days and in weeks, the span as years, months and days, and the calendar dates that the 30, 60 and 90 day marks and the 6 month, 1, 2, 5 and 10 year marks fall on, each with the days to or since it. The date is sent by post rather than in the web address, so it does not appear in the address bar, in a link or in a server request log. It is date arithmetic and nothing else.
