Where the figure comes from
Merck: gestation in goats is 145-155 days, averaging 150.
Worked out from Merck Veterinary Manual, The Reproductive System in Animals (gestation periods table) and 4 other sources.
2026-09-06 is 98 day(s) past the expected due date; overdue animals warrant a veterinary check.
A planning estimate from published mean gestation lengths, not veterinary advice. Individual animals, breeds, litter size and sex of the offspring all shift the date; confirm pregnancy and timing with your veterinarian.

How this is worked out

4 steps
  1. Goat (doe): published mean gestation of 150 days.
  2. 2026-01-01 + 150 days = 2026-05-31 (Sunday), the expected kidding date.
  3. Normal range 145-155 days puts the window at 2026-05-26 to 2026-06-05.
  4. On 2026-09-06 the animal is 248 days into gestation, -98 to go.
