📅 Being born on leap day vs ⚡ Struck by lightning
Share card
You're 10.5× more likely to be born on leap day
than to be struck by lightning
Periods differ: Being born on leap day is framed as per birth (calendar), while Struck by lightning is lifetime (US). The multiplier is a raw ratio of the 1-in-X figures — not a normalized lifetime risk. Compare cautiously.
How we calculated this
Each figure is “1 in X.” The larger X is the rarer event. Dividing that number by the more common one gives the multiplier: you're 10.5× more likely to be born on leap day. When the periods differ, this is a raw ratio of those figures, not a lifetime-normalized risk.
