# Seasonplot

> Independent garden-planning references from NOAA 1991–2020 agricultural climate normals, the 2026 Census Gazetteer, and source-bounded university extension guidance. No official affiliation or forecast guarantee.

## Content
- /frost-dates/: National source finder and coverage overview.
- /states/: State hubs are linked from the frost-date finder; each shows actual station and Census coverage.
- /frost-dates/{station-id}/: Station-specific conditional freeze probabilities, annual freeze occurrence, quality flags and original source.
- /locations/{place-slug}/: Geographic reference lookup with Census identity, nearest-station distance and limitations; not a locally validated planting calendar.
- /vegetables/: Crop guides with regional evidence, maturity starting methods and source links.
- /regional-guides/: Colorado, Central North Carolina, and explicit North/Central/South Florida references. Source qualifiers and withheld ambiguous values are preserved.
- /fall-planting-calculator/: Count back from a user-chosen harvest target, not an automatically assumed freeze deadline.
- /methodology/: Source provenance, conditional probability definitions, geography, quality gates and reuse limits.
- /contact/: Contact the project owner at hello@seasonplot.com for corrections.

## Interpretation
Freeze-date probabilities are conditional on a cold season containing a 32°F freeze, not all years. Annual freeze occurrence is separate. Spring means last occurrence on or later; fall means first occurrence on or earlier. Year-wrap offsets are retained. Geographic proximity does not validate garden climate or crop suitability. Regional planting guidance must not be extrapolated nationwide. No affiliate links, analytics or ad scripts are active.
