How to use this calculator
Enter finish date, time and zone. List stages in order with shortest and longest observed minutes and whether they need active attendance. Set quiet hours.
Duration means elapsed minutes, including across daylight-saving changes. Two consistent scenarios use all minimum or all maximum durations. Calendar exports use the longer scenario; quiet-hour flags inspect both.
A worked example
For a November 7, 2026 finish at 10:00 in New York, the example stages start November 6 between 10:15 and 15:00.
Can this decide when dough is ready?
No. Fermentation depends on conditions and dough behavior. Supply observed recipe timings and assess readiness yourself; this is a schedule, not a recipe or safety check.
Which calendar and years are supported?
Use Gregorian dates from 1900 through 2100, with results in that range. Daily plans allow up to 366 dates; dark-sky searches allow 31 nights. Durations, capacities and policy rules are supplied by you. Astronomy uses the bundled Astronomy Engine, sea-level geometry and browser time-zone rules. Timed exports use UTC instants; date-only events do not assign a clock time. Copy, CSV and print include calculation assumptions. Nothing is booked or scheduled outside this page.
What happens to my dates?
Calculations run on your device. Saving a calculation is optional and keeps it in this browser. A setup link contains the dates and settings you entered; anyone with the link can read them. Use one tab per saved calculator. Clear saved data from Privacy & settings.
