International scientists have abolished the leap second, ending a 50-year practice of adjusting clocks to match Earth's irregular rotation.
Why it mattersThe cancellation of the leap second represents a long-standing scientific practice ending.
Scientists are abolishing the leap second, a practice used to keep atomic time aligned with Earth's rotation, in favor of a leap hour. This change aims to prevent infrastructure failures and simplify timekeeping.
Why it mattersThis decision by world timekeepers to replace leap seconds with leap hours is a major shift in how we manage time.
