Rabbit Age Calculator
Convert rabbit age to human years.
Find your rabbit stage from kit to senior and learn what age-related health care to expect at each life stage.
How Rabbit Age Is Calculated in Human Years
Rabbits age much faster than humans, especially in their first year. The conversion is not linear — rabbits mature rapidly early in life, then age more gradually.
Rabbit-to-Human Age Conversion Scale:
| Rabbit Age | Human Equivalent |
|---|---|
| 2 months | ~2 years |
| 6 months | ~16 years |
| 1 year | ~21 years |
| 2 years | ~27 years |
| 3 years | ~33 years |
| 5 years | ~45 years |
| 7 years | ~57 years |
| 10 years | ~75 years |
| 12+ years | ~83+ years |
Approximate Formula for Adult Rabbits (1+ years):
Human Age ≈ 21 + (Rabbit Years − 1) × 6
Worked Example: A 5-year-old rabbit:
- Human Age ≈ 21 + (5 − 1) × 6 = 21 + 24 = 45 human years
Life Expectancy by Breed:
- Small breeds (Dutch, Mini Rex): 10–12 years
- Medium breeds (Holland Lop): 8–12 years
- Large breeds (Flemish Giant): 5–8 years
- Indoor rabbits live significantly longer than outdoor rabbits on average
Key Health Milestones:
- Sexual maturity: 3–6 months depending on breed
- Considered “senior” at 6+ years (small breeds) or 4+ years (large breeds)
- Spayed/neutered rabbits typically live 2–3 years longer
- Annual vet checkups recommended; biannual after age 5
