Against the frost risk in Islamabad
Why these dates
Killed by frost. Genuinely tropical, and not a temperate garden crop under any management.
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. Cassava are timed with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Islamabad.
Hardiness is not the obstacle here. Islamabad is zone 10a, comfortably inside the range this crop is rated for, so an established plant should come through an average winter without protection.
The median frost-free season here is 336 days, against 240 to 330 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
