Kombucha Calendar
Reckonersweight 1reckoner · computes, doesn't store
Your kombucha does not care that you have a life; it ferments on its own schedule and expects you to keep up. The Kombucha Calendar computes the timing of a brew — when a batch started on a given day will be ready, first ferment through second — so you are bottling on purpose instead of by apologetic surprise. It reckons the dates and stores nothing; the scoby keeps its own counsel.
This is not a screenshot. It's the real tool, running right here — go on, put something in it.

Questions people ask
How do I know when my kombucha will be ready?
Give it your start date and how long you ferment, and it computes when to taste, bottle, and finish. The calendar arithmetic is done for you; the tasting judgement stays yours.
Is this kombucha tool private, and does it need an account?
No account, no signup, nothing stored. It is a single HTML file running offline in your browser — it computes your brew dates on the spot and nothing leaves the page. Yours forever, like a good scoby.
Does it handle the second ferment too?
Yes — it reckons the full timeline, first ferment and second, from a single start date. The fizzy part of the schedule is the part most worth getting right.
