Since the 1960s, scientists have used atomic clocks to precisely monitor time. However, on June 29, scientists watching these clocks noticed an anomaly: it was Earth’s shortest day in recorded history.
According to a report by timeanddate, on June 29, Earth completed a rotation in 1.59 milliseconds less than 24 hours, highlighting a recent trend that has seen the planet’s rotation speed up. In 2020, the Earth achieved its 28 shortest days since daily measurements began.
