What this calculator does
Projects a kindling window for a rabbit doe from the mating date.
What your result means
Days remaining to expected kindling, based on the 31-day average.
Formula and working
days remaining = gestation length − days elapsed; progress = days elapsed ÷ gestation length × 100
- 1
Collect the inputs
Days since mating = 16 days; Gestation length used = 31 days
- 2
Apply the formula
days remaining = gestation length − days elapsed; progress = days elapsed ÷ gestation length × 100
- 3
Result
Days until expected kindling = 15 days
