73660, near Reydon, OK: the frost window
Around 04/15 is the usual last spring frost, about 230 days away. Fall's first freeze usually shows up around 10/27, roughly 194 days after the last spring frost.

Stretching the season past the first frost
Reydon's growing season runs out in roughly 9 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.
Why 04/15 isn't a guarantee
04/15 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/01 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/29 and only about 1 year in 10 sees frost after that.
