Will we lose a second in 2029?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
This refers to potential "leap second" adjustments in timekeeping. Earth's rotation is gradually slowing due to tidal friction with the Moon, reuiring occasional one-second adjustments to keep atomic clocks synchronized with Earth's rotation. However, in November 2022, authorities voted to eliminate leap seconds by 2035, so the 2029 adjustment may not happen. The concern isn't "losing" time but coordinating our precise timekeeping systems with Earth's irregular rotation.
