Your working data
Edit cells directly or import a CSV. Download “Input CSV” for the required column names. Up to 200 rows; scroll the table sideways for additional fields.
Detailed analysis
Exports include all results, regardless of the search filter. The HTML report includes assumptions and source data; use your browser’s Print command for PDF.
Chart shows the first 20 rows; negative values use a warm color. Click table headers to sort.
Compare up to four scenarios
Capture the current inputs, change assumptions and capture again. Scenarios are included in downloaded projects.
What this model includes
Dates follow your supplied offsets, not local growing advice. For direct-sown crops use zero transplant days. Weather, variety and frost risk can change actual dates.
Import and save safely
CSV imports use your current assumptions. Project files restore assumptions, rows and saved scenarios. No automatic saving: download a project before closing this page. Imports are limited to 10 MiB and 200 rows. Calculations run in your browser; the site’s advertising and analytics follow its privacy policy.

Questions & answers
What does Seasonal Garden Calendar calculate?
Create crop-specific sowing, transplant and estimated harvest dates from your chosen seasonal anchor and succession intervals.
What are the important limitations?
Dates follow your supplied offsets, not local growing advice. For direct-sown crops use zero transplant days. Weather, variety and frost risk can change actual dates.
Can I continue my work later?
Yes. Save a project JSON file and reopen it with Import CSV / project. It contains the working data, assumptions and up to four scenarios. Nothing is saved automatically.
What CSV columns do I need?
crop, sow, transplant, maturity, batches, spacing. Download Input CSV for a compatible example. CSV imports keep your current assumptions.
Are these example figures current industry benchmarks?
No. They are illustrative values to demonstrate the model. Replace them with figures appropriate to your situation.
Can I add this plan to my calendar?
Open Results & chart and choose Download calendar (.ics). It creates all-day sowing, transplant and estimated-harvest events. Review them before importing into your calendar.
