How these dates are worked out

Each crop has temperature limits and timing from university extension guides: how cold a night it can take, how much heat it can stand, how long it takes to mature, and how far before or after the last frost it goes in. Those are checked day by day against the Anchorage Merrill Field station's NOAA 1991–2020 climate normals (average highs, lows, rain and frost dates). Dates are estimates for a typical year; a sheltered yard, a slope or a cold pocket can shift them by a week or two.
