The rule
Start indoors or direct-sow; set out / sow 3–4 weeks before the last frost. [src]Cited: University of New Hampshire Cooperative Extension — “Growing Vegetables: When to Plant Your Vegetable Garden”

Days to maturity: 60–85 days [src]
Method: Start indoors or direct-sow. Frost tolerance: frost-hardy (derived from the planting timing above).
Because lettuce is frost-hardy and matures in about 60–85 days, it's a strong fall crop — sow it in mid-to-late summer so it finishes before your first frost.
