Days to maturity can be counted from sowing or from transplanting. Those two descriptions produce different dates, even when the seed packet shows the same number. Before building a harvest plan, check which starting point your chosen duration uses.
The Sowing and Harvest Date Planner distinguishes seedlings raised for transplant from crops sown directly into the bed. It takes your entered durations and turns them into calendar milestones. It does not select a sowing season for a city or crop.
A transplant based eighty eight day example
Suppose the sowing date is 15 October 2026, germination is expected after seven days and transplanting after 28 days. If first harvest takes 60 days counted from transplanting, the complete interval from sowing is 88 days.
The dates become 22 October for germination, 12 November for transplanting and 11 January 2027 for first harvest. With a 21 day harvest window, its inclusive last day is 31 January 2027.
The window ends 20 days after first harvest because the first date is already day one. Adding the whole 21 days again would shift the endpoint one day later than the worksheet's stated inclusive window.
Direct sowing removes the transplant stage
Select direct sowing for a crop that stays where it was sown. The tool hides the transplant inputs and counts maturity from sowing. In the same date example, 60 days from 15 October gives first harvest on 14 December 2026, without an expected transplant milestone.
For raised seedlings, the harvest basis can still be sowing if that is how the chosen duration is specified. The worksheet checks that the resulting harvest is not before germination or the entered transplant date.
Use timings that belong to the variety
The durations are editable assumptions. Seed packet information, crop stage, local conditions and your own records matter more than preserving the example values. The calculator handles date arithmetic, including month boundaries and leap years; it does not observe growth or predict a particular harvest.
Pakistan's different altitudes and growing conditions should not be reduced to one nationwide starting date. Set a locally appropriate sowing date before reading the calendar as a useful plan. The October example demonstrates the calculation, not a recommendation for every location or vegetable.
Plan neighbouring batches separately
A first harvest date does not mean constant production throughout the entered window. It is a planning range whose actual pattern remains crop dependent.
Use Succession Sowing Planner when repeating a directly defined sowing batch at fixed intervals. Keep its maturity figure on the from sowing basis it requires rather than copying a transplant counted number unchanged. For the number of seedlings to start ahead of this plan, Seed Tray Planner can allocate cells and medium.
