11424, near New York, NY: the frost window
Around 04/02 is the usual last spring frost, about 217 days away. Fall's first freeze usually shows up around 11/14, roughly 226 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts New York in Zone 7b (5 to 10°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
Stretching the season past the first frost
New York's growing season runs out in roughly 11 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.
Why 04/02 isn't a guarantee
04/02 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/20 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/13 and only about 1 year in 10 sees frost after that.
