Free cow pregnancy calculator: breeding or AI day planner with common cattle gestation anchors (~283 days), wider 277–293 day band, symmetric calving window, days elapsed, trimester-style thirds, animated progress and nine-phase ladder—for education only, not veterinary advice.
Important: This page is an educational herd calendar planner for typical beef and dairy cattle gestation—not veterinary diagnosis, ultrasound scheduling, or calving protocols. Breed, parity, twins, and AI timing all shift real outcomes; work with your veterinarian or herd advisor.
🐮Summary: Enter your best estimate of breeding or successful AI day, pick a gestation length (many herds plan around 283 days, the “9 months + 10 days” rule of thumb), and an as-of date. You will get a due window, day counts, trimester-style bands, and 🍀 animated nine-phase “pasture ladder” bars—calendar math with barn vibes, not a replacement for your vet.
