There are a total of three days this summer when the moon will be around its furthest distance from Earth’s equator, resulting in a minuscule increase in the Earth’s spin speed. One of them occurred on July 9, when the day was shortened by nearly 1.4 milliseconds. The remaining two days are predictions from scientists:

Tuesday, July 22, is expected to be the second of three days in 2025 where more than a millisecond could be shaved off the day due to Earth's rotation

Scientists predicted that Tuesday will be a fraction of a second shorter than normal as the Earth's rotation is moving faster.
