Why these dates

Start indoors eight weeks before the last frost and plant out two weeks before it. Stocks need cool nights, below about 15C, for several weeks to initiate flower spikes, so early planting is not optional - a late-planted stock grows into a leafy plant that never blooms.

Hardy to about -8C. In zone 8 and warmer the sensible approach is autumn planting for late-winter flowers, and in hot climates it is a winter crop only.

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. Stocks are timed from 8 weeks before that frost for an indoor start, with planting out 2 weeks before it, and this page simply resolves those offsets against the frost date computed for Benin City.

Benin City sits in zone 12b, which is milder than this crop wants, and a winter that never really arrives is its own problem. The dates below still describe the right time of year; the open question is survival rather than timing.
