    About this moment

    Leap seconds abolished is expected 2035. The exact day has not been announced yet.

    In November 2022 the General Conference on Weights and Measures resolved that leap seconds will stop being added to UTC by 2035 at the latest, letting civil time drift slowly from Earth's rotation. The exact year of the last leap second has not been fixed, so this is a deadline rather than a scheduled instant.

    The source has announced a date range. An exact day has not been confirmed.
