Earth's rotation speeds up, causing shorter days in July due to Moon’s new alignment on these dates

Earth is set to experience unusually short days in July and August 2025. The Moon's orbital position is subtly accelerating Earth's rotation. These days will be milliseconds shorter, impacting precision systems. Global timekeepers are considering a negative leap second around 2029. This adjustment is needed to maintain accuracy. The change is scientifically important for satellite communications and GPS systems.
