Your age gets weird
Fun, not fate: Animal values use broad lifespan
comparisons, space values use average orbital periods, and life stats
use friendly everyday estimates. Real biology and astronomy vary.
No time machine required
How the math works
Calendar-aware
Years, months, and days follow your local calendar, including leap years and different month lengths.
Your timezone
โRight nowโ comes from your device in your timezone.
Honest precision
Nanoseconds are derived from JavaScript's millisecond clock, so we label them as an estimate.
Frequently asked
Questions, answered
Is my birth date saved anywhere?
No. Every calculation happens locally in your browser. Nothing is uploaded or stored.
Why can age results differ between calculators?
Some calculators treat a month as a fixed number of days. This one uses actual calendar boundaries in your local timezone.
Are the animal ages scientifically exact?
No. Species, breeds, and individuals age differently. We show both a lifespan-based comparison and a deliberately playful rule of thumb.
