Questions

Which frost date do the crop weeks use?
Weeks after the frost-free date use the median last 32°F date, March 11, when the guide does not name a probability. Weeks before the first freeze use the median first 32°F date, November 20. Both medians are 50% dates in the NOAA 1991–2020 normals for the station on this page. The page says when that anchor was used.
Where do the crop dates come from?
Crop dates come from the extension guide cited on this page, not from a second calendar invented here. The publisher and the title are printed with the source note. A month without a day is expanded to the first and last day of that month, and the page says so. A phrase without two dates stays a phrase.
Is this planting calendar a forecast?
No. The frost dates are 1991–2020 climate normals at the station 7.3 miles from the city point. The crop windows are the cited guide’s ranges, shifted only when that guide itself used weeks. A cold spring can still fall past the median. The National Weather Service forecast covers a particular night. This page does not.
