Llama Pregnancy Calculator – Due Date & Progress
Llama Pregnancy Calculator
This calculator estimates a llama’s expected due date, a practical due window, and the current gestation progress based on a breeding date and a reference date. It is designed to be simple, fast, and useful for day-to-day planning.
How the calculation works
The core idea is adding a gestation length (in days) to the breeding date:
\( D_{due} = D_{breed} + G \)
To reflect natural variation, the calculator can also show an earliest and latest due date window:
\[ D_{min} = D_{breed} + G_{min} \] \[ D_{max} = D_{breed} + G_{max} \]
Gestation progress
Progress is calculated from the number of days between the breeding date and the reference date:
\[ d = \max(0, D_{ref} - D_{breed}) \] \[ p = \frac{d}{G} \times 100 \]
If your reference date is before the breeding date, the calculator treats the pregnancy day count as 0 to avoid confusing negative results.
