The Earth is spinning faster than ever - what is going on?

Ever wonder if our 24-hour day is really fixed? In this video we reveal a mind-blowing Earth science story: the planet’s rotation is speeding up so much that July 9, 2025 could be the shortest day ever measured.

Astronomers confirm Earth spun incredibly fast in July 2024 – the day of July 5, 2024 was 1.66 milliseconds shorter than 24 hours
– and data now shows July 9 (and two other summer dates) will each trim 1.3–1.5 ms off a day
. Why is this happening? We explain it with stunning visuals: the Moon’s distant position this summer weakens its tidal brake, mass shifts inside Earth (like melting polar ice and core motion) are altering spin, and even subtle changes in Earth’s liquid core have sped up the surface rotation
. By the end, you’ll see how cosmic and geophysical forces conspire to tweak time. We break down the science of day length variation – from atomic clocks and leap seconds to gravitational pulls and core dynamics – in simple terms. (Hint: we might even need a “negative leap second” to keep our clocks synced
Key Takeaways:
Day length can change: A “day” isn’t exactly 24:00:00. Earth’s rotation wobbles by tiny amounts (milliseconds) due to complex factors

Record-short days: July 5, 2024 set a new record for shortest day (-1.66 ms)

. Now scientists predict July 9, July 22 and Aug 5, 2025 each will be ~1.3–1.5 ms shorter

. Even our seasonal cycle usually makes midsummer the shortest days

Why Earth speeds up: When the Moon is far from Earth’s equator this summer, its tidal drag is reduced

. Meanwhile, changes deep inside Earth – like the liquid core slowing – transfer angular momentum to the crust, speeding up the surface
. Melting ice and shifting atmospheric mass also play roles
.
Impact on timekeeping: With the day shortening, global timekeepers are preparing to subtract a leap second for the first time

. We explain what a “negative leap second” means, and how precise clocks (like GPS satellites) stay in sync even as Earth’s spin fluctuates
.

Is today the shortest day ever? Our planet is doing something strange, it's spinning faster than usual, according to *science news**. In fact, on July 9th, 2025, we may experience a record due to this change in **orbital velocity**, a phenomenon also related to **physics* and **inertia**, and **earth science**.
