Why these dates

Sow from about ten weeks after midsummer into ground vacated by an earlier crop. It germinates in cool soil, so a late sowing is a feature rather than a compromise.

Survives -15C without protection. Frost does not damage the leaf at all, which is why it is a winter crop everywhere it is grown.

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. Lambs lettuce are timed for direct sowing 10 weeks after it, and this page simply resolves those offsets against the frost date computed for Perm.

The median frost-free season here is 135 days, against 60 to 80 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
