The planet\u2019s rotation fluctuates as it travels around the sun, and measurements suggest we\u2019re losing more than a millisecond during the long days of summer.<\/p>\n

It wouldn\u2019t be summer without the stretched out days. The dawns break early and the dusks come late, affording more time for lazy beach trips and long barbecues under the slow curve of the sun.<\/p>\n

But when it comes to the full astronomical day \u2014 a single rotation of planet Earth in which the hour hand moves twice around a standard clock \u2014 some of this year\u2019s shortest are happening in July and August.<\/p>\n

This week has seen the shortest days of the year so far. According to data<\/a> from the U.S. Naval Observatory<\/a> and the International Earth Rotation and Reference Systems Service<\/a>, Tuesday\u2019s rotation was about 1.34 milliseconds less than 24 hours.<\/p>\n

More quick spins are expected this week, later this month and in early August, according to predictions from the website Time and Date<\/a>.<\/p>\n<\/div>\n<\/div>\n

This isn\u2019t completely out of the ordinary: Our world\u2019s spins have been faster than usual lately. The average day has mostly shortened over the past decade, and within the past five years or so, the full rotation has clocked in at a hair less than 24 hours more often than not. Factors driving the change include movements at Earth\u2019s core, atmospheric changes and the moon\u2019s position.<\/p>\n

But long-term trends do not suggest that the days will shorten in perpetuity. In fact, it is just the opposite. For many millenniums, the days have been growing longer. A Tyrannosaurus rex that lived 70 million years ago would have experienced an average daily rotation of about 23 1\/2 hours, studies<\/a> have found.<\/p>\n
