🍞 Sourdough Timing Calculator

Plan your starter feedings and two-day bread-making schedule. All times update as you edit.

1. Starter Estimate

Feeding Start date & time Rise (hours) Estimated peak Notes
Feeding #1 (1:1:1 from cold main starter) Can stay out until next day
Feeding #2 (1:3:2.9 added to Feeding #1) Time peak to when you want to make bread
Starter peak estimates are based on your entered rise times; actual fermentation varies with temperature and starter activity.
