Why these dates

Sow indoors eight weeks before the last frost and plant out two weeks before, or sow direct two weeks before it. The seed is large and germinates best in the dark, so cover it properly. Self-seeds readily on light soil and comes true.

Hardy to about -8C, so autumn sowing works in zone 8 and milder. Needs sharp drainage above all: it rots in a wet winter long before the cold reaches it.

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. Honeyworts 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 Cairo.

Cairo sits in zone 10b, 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.
