How to Use This Calculator
  1. Enter Graft Day of Year.
  2. Review Queen Emergence and Expected Laying Start.
  3. Use Graft Date and Cell Capped to inform your decision.
  4. Use the chart to visualize the results and explore different scenarios by adjusting inputs.

What each input means

Graft Day of Year
Day of year for grafting (1 = Jan 1, 120 = Apr 30, 152 = Jun 1). Best results grafting April through June.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Graft Day of Year = 120 = 1 input(s) provided
  2. Calculate Queen Emergence
    Queen Emergence = doyToDate(emergenceDate)
    May 11 = May 11
  3. Calculate Expected Laying Start
    Expected Laying Start = doyToDate(layingDate)
    May 23 = May 23
  4. Calculate Graft Date
    Graft Date = doyToDate(graftDate)
    Apr 30 = Apr 30
  5. Calculate Cell Capped
    Cell Capped = doyToDate(cappedDate)
    May 5 = May 5
