Why these dates

Start indoors five weeks before the last frost and plant out two weeks after it. It needs a longer warm run than a pumpkin, so it is marginal in cool summers.

Killed at 0C. The wax bloom that makes it store so well only develops on fully mature fruit, which needs the whole season.

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 melons are timed from 5 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 Halifax.

The median frost-free season here is 204 days, against 110 to 140 days to maturity for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.
