Why these dates
Start indoors six weeks before the last frost and plant out two weeks before. A check to growth at any point gives you a loose head rather than a dense one.
Takes around -3C. The long season means a late sowing can be caught by the first autumn frost before it has hearted.
Seed packets and extension guides express timing as weeks either side of the last spring frost, because that is the only reference point that travels. Iceberg lettuce are timed from 6 weeks before that frost for an indoor start, with planting out 2 weeks before it, and this page simply resolves those offsets against the frost date computed for Luxor.
