Against the frost risk in Donetsk
Why these dates
Spring sowings feed you through summer; the sowing made twelve weeks before first frost is the one that carries you through winter.
Survives -12C and sweetens markedly below freezing as starches convert to sugars. Frost is a feature of this crop, not a threat.
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. Kale 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 Donetsk.
The median frost-free season here is 179 days, against 55 to 75 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
