extra second inserted or removed to keep civil time in sync with the Earth's rotation
AI overview
A leap second is an extra second that is occasionally added to our clocks to keep official timekeeping aligned with how fast the Earth is actually spinning. This adjustment matters because Earth's rotation is gradually slowing down, and without these corrections, our civil time would gradually drift out of sync with the sun's position in the sky.
