Why these dates

If your frost-free season is shorter than 110 days, start indoors and choose a smaller cultivar. Giant pumpkins are a long-season crop, not a beginner one.

Foliage dies at the first frost, but mature fruit tolerates a light touch. Harvest before a hard frost or the flesh will not store.

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. Pumpkins are timed from 3 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 Ulyanovsk.

The median frost-free season here is 164 days, against 90 to 120 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
