Elephant Pregnancy Calculator

Elephant pregnancy calculator

This calculator estimates an elephant pregnancy timeline from a known conception date and a configurable pregnancy length in days. It returns an estimated due date, a delivery window, pregnancy progress, and a milestone table that you can export.

Species selection and pregnancy length

Elephants are commonly recognized today as three living species: African bush elephant, African forest elephant, and the Asian elephant. Each can have a different typical pregnancy length, so this calculator uses your selection to set a sensible default value and show a typical range as context.

Important - the pregnancy length field is always editable because real timelines vary between individuals and populations, and field protocols may define specific assumptions.

How the due date and progress are calculated

The calculator uses simple date arithmetic:

\( \text{DueDate} = \text{ConceptionDate} + \text{PregnancyDays} \)

\( \text{ElapsedDays} = \max(0, \text{ReferenceDate} - \text{ConceptionDate}) \)

\( \text{RemainingDays} = \max(0, \text{DueDate} - \text{ReferenceDate}) \)

\( \text{Progress\%} = \frac{\text{ElapsedDays}}{\text{PregnancyDays}} \times 100 \)

Milestones table and detail level

Simple mode shows a compact set of checkpoints (start, quarter points, and end). Detailed mode adds extra checkpoints (for example, around 5%, 15%, 33%, 67%, and 95%). The table is always displayed in both modes.

Customize columns and export

Use Customize Columns to reorder or hide columns for your workflow, then export the visible columns to CSV or Excel. The reset button restores both the inputs and the default table columns layout.

Overdue highlighting

If your reference date is after the estimated due date, the table highlights an overdue state. This is a mathematical comparison based on your inputs, not a medical or veterinary diagnosis.
