Against the frost risk in Novomoskovsk
Why these dates
Plant out two weeks after last frost, once nights are reliably above 12C. A second sowing in midsummer replaces plants that have gone to flower.
Damaged at 1C, before any actual frost forms. If your forecast shows 2C, basil should already be indoors.
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. Basil are timed from 4 weeks before that frost for an indoor start, with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Novomoskovsk.
The median frost-free season here is 159 days, against 50 to 70 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
