Ladies Gentlemen, please let me tell you that in IERS/EOC data, [https://hpiers.obspm.fr/eop-pc/products/combined/C04plot.php?date=2&dimx=1200&dimy=900&tver=1&graphe=55&year1=2020&month1=1&day1=1&year2=2031&month2=12&day2=31&langue=1&SUBMIT=Submit+request Δomega] and [https://hpiers.obspm.fr/eop-pc/products/combined/C04plot.php?date=2&dimx=1200&dimy=900&tver=1&graphe=5&year1=2020&month1=1&day1=1&year2=2031&month2=12&day2=31&langue=1&SUBMIT=Submit+request ΔLOD] (from [https://hpiers.obspm.fr/eop-pc/index.php?index=C04&lang=en this] page) supported by Vondrak filter's [https://hpiers.obspm.fr/eop-pc/index.php output] one can see that in late 2022 earth is decelerating making positive leap second more probable than negative. Indeed only God knows how long it will last. With regards and friendship Georges Theodosiou. [[User:Georges T.|Georges T.]] ([[User talk:Georges T.|talk]]) 16:48, 15 December 2022 (UTC)
:The Earth's rotation rate is seasonal. It is clear from the charts you referenced that the Earth spins faster during Northern Hemisphere summer.s. To get a useful prediction of the future rate of rotation of the Earth you need to look at a year's worth of data.
:The IERS has predicted that the Earth's rate of rotation will continue to be slower than one per 86,400 seconds over the next year. My guess, based on projecting the IERS prediction further into the future than one year, is that we will have a negative leap second somewhere around the end of this decade.
