Typically, the last spring freeze lands around 03/12, roughly 196 days out. Fall's first freeze usually shows up around 11/13, roughly 241 days after the last spring frost.

Stretching the season past the first frost
With roughly 11 weeks until Mesilla's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
How much risk comes with planting early here
03/12 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/23 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/02 and only about 1 year in 10 sees frost after that.
