Around 03/27 is the usual last spring frost, about 211 days away. The first fall frost typically arrives around 11/04, about 224 frost-free days later.
The USDA Plant Hardiness Zone Map puts Datto in Zone 7b (5 to 10°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 03/27 isn't a guarantee
03/27 is the middle of 30 years of NOAA records, not a promise. Plant by 03/10 and you're betting against frost in roughly 9 years out of 10. 04/10 is the safer bet, historically only a 1-in-10 chance of frost that late.
