24 hours sober

24 hours sober is one exact circuit of the clock from the time you stopped, not the next midnight.

Stop at 6pm and this mark is 6pm the next day. The completed-day count may still say 0 or 1 then, because days change at local midnight. Around a clock change, 24 hours can also fall at a different time of day than you expect. The calculator lists both.

Set your quit date and the calculator marks the day.

Leave the time blank to count from midnight. Today is day 0 until the next midnight.

About this mark

Does 24 hours mean the next midnight?

No. Midnight is when the day count goes up. 24 hours is the same time tomorrow, measured in real elapsed time.

What if I don’t remember the time?

Leave the time blank. The calculator then starts at midnight, so 24 hours and the first completed day land together, except on a daylight-saving night.
