"During one orbit around the Sun, Earth rotates about its own axis 366.26 times" Wikipedia main 'Earth' article

The 'solar vs sidereal' fiction that the Earth is into its next full rotation after 23 hours 56 minutes 04 seconds and the 3 minute 56 second difference to 24 hours provides the basis for this eccentric notion that days and rotations fall out of step within the confines of an annual circuit. Currently they are jettisoning this fiction for an new one which conjures an non astronomical assertion out of thin air an assigns a rotation once in 24 hours back in the year 1820 -

"At the time of the dinosaurs, Earth completed one rotation in about 23 hours," says MacMillan, who is a member of the VLBI team at NASA Goddard. "In the year 1820, a rotation took exactly 24 hours, or 86,400 standard seconds.. Since 1820, the mean solar day has increased by about 2.5 milliseconds." NASA

Every single organization out there gets its wrong - they assume that the Earth's rotation in isolation provides the cyclical basis of timekeeping however the parent observation for timekeeping is the 1461 days across 4 years including February 29th or its dynamical equivalent - 1461 rotations within the confines of 4 orbital circuits of the Earth around the Sun. The parent observation then goes in two different directions ,for interpretative purposes the Earth turns 365 1/4 times per circuit while,for predictive astronomical purposes, the parent observation is formatted in a 365/366 rotation framework with the February 29th leap day rotation closing out four annual cycles to the nearest rotation.

The line-of-sight observation of Sirius and its first annual appearance just far enough to one side of the Sun's glare provides the defining observation for the Earth's orbital position in space so that the Earth's orbital motion and the Sun's central position provide the only possible three way reference for determining the number of rotations within an orbital circuit.

How humanity came to believe in 1465 rotations in 4 orbital circuits will some day be treated for the awful aberration that it actually is even though it forms a dominant perspective in this era.

Time to take the 1461 rotations in 4 annual circuits perspective as the fundamental unit of timekeeping and undo the damage and chaos created over the centuries.
