Each window is a range, not a single day. Earlier in the range buys you a longer season; later in it buys you a safer one.
Pears through the year
Against the frost risk in Giza
Why these dates
Dormant planting, as for apples. Pears flower a week or two earlier than apples in most climates, which sounds trivial and is not: that fortnight moves bloom squarely into the window when late frosts still happen, and it is the single biggest reason pear crops fail in marginal areas.
The tree itself is fully hardy. The early bloom is the exposure. Where late frosts are common, a site with cold-air drainage - a slope rather than a hollow - is worth more than any amount of winter protection.
Pears are planted once and then left in place, so there is no sowing offset to resolve. What matters in Giza is the shape of the year: this crop is dormant through the winter and is planted while it sleeps, any time between leaf fall in autumn and the restart of growth in spring, so long as the ground is neither frozen nor waterlogged. That is why the window below spans the cold months rather than sitting in the middle of the growing season.
Giza 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.
One caution specific to warm climates: this crop needs roughly 700 hours below 7.2°C (45°F)45°F (7.2°C) over winter before it will flower properly, and the coldest month in Giza averages 13.1°C (55.5°F)55.5°F (13.1°C). Low-chill varieties exist for exactly this situation and are worth seeking out by name.
Do not expect a crop in the first year. A plant set out now should give its first worthwhile pick around year 4, and will then produce every year after that, which is what makes the planting decision worth getting right the first time.
