IERS Confirms No Leap Second Will Be Added at End of December 2026

The International Earth Rotation and Reference Systems Service (IERS) issued its latest bulletin. The bulletin states that no leap second will be introduced at the end of December 2026. Leap seconds are occasional one‑second adjustments to Coordinated Universal Time. They are added when Earth's rotation deviates from atomic time standards. The decision means the UTC clock will continue unchanged through 2026. Users of time‑sensitive systems can plan without expecting a February 29‑type adjustment. The announcement follows the regular schedule of IERS assessments. Future leap‑second considerations will be revisited as the next evaluation period approaches.
