Around 05/16 is the usual last spring frost, about 261 days away. The first fall frost typically arrives around 09/24, about 128 frost-free days later.
The USDA Plant Hardiness Zone Map puts New England in Zone 4b (-25 to -20°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
What to do before the first frost

Why 05/16 isn't a guarantee
05/16 is the middle of 30 years of NOAA records, not a promise. Plant by 05/06 and you're betting against frost in roughly 9 years out of 10. 05/29 is the safer bet, historically only a 1-in-10 chance of frost that late.
