About how long

Span uses this as the middle of the range. The months fade around it rather than stop, because no one knows exactly.

How this is estimated

Life expectancy for your country and sex comes from UN World Population Prospects 2024 (estimates for 2023), adjusted for the years you have already lived. No future medical progress is assumed, so real odds are probably a little better. It is a population average, not a forecast about you. Dogs are based on a study of 584,734 UK dogs (O’Neill et al., 2024), cats on UK cat life tables (Teng et al., 2024). If you enter what you know, Span uses it instead of averages. Your details stay on this device.

One direction for the month: a person, a habit, a place, a feeling.

A note to a month ahead

Span keeps it sealed, even from you, until the month you choose.

Only on this device. A backup keeps it too.
