18346, near Mount Pocono, PA: the frost window

Zone 6a

The last spring frost here typically falls around 05/06, about 251 days from today. Fall's first freeze usually shows up around 10/08, roughly 154 days after the last spring frost.

Stretching the season past the first frost

Mount Pocono's growing season runs out in roughly 6 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 05/06 isn't a guarantee

05/06 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/21 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/23 and only about 1 year in 10 sees frost after that.
