Winter squashes through the year
Against the frost risk in Delhi
Why these dates
Work backwards: sow date plus days to maturity plus two weeks of curing must land before your first autumn frost. That constraint, not the spring date, is what rules this crop out in cold climates.
A light frost that kills the leaves will not ruin ripe fruit, but it stops any further ripening. Unripe squash does 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. Winter squashes 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 Delhi.
