The quite understand the silence regarding this awful notion that there are 366 1/4 rotations inside an orbital circumference when,in fact, there are 365 1/4 with the latter correct value drawn from the parent observation of the additional February 29th rotation and what it represents in dynamical terms.

About 20 years ago anyone who picked up a textbook would have read that the Earth doesn't turn once in 24 hours but in 23 hours 56 minutes 04 seconds -

The idea was that the extra 3 minutes 56 seconds to 24 hours accumulates over an orbital period and that generates the extra rotation than 24 hour days -

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

Like all catastrophic events where considerable damage and chaos ensues, the consequences are brutal including the inability to react to this situation where the emergence of the Lat/Long system in tandem with the 24 hour system keeps days and rotations in sync.

Today they even have created a new fiction conjured out of thin air in order to create a division between timekeeping and the rotation of the Earth where they now reject the 'solar vs sidereal' fiction and introduce a non cyclical and non astronomical assertion -

"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.." NASA

I hope reader here enjoyed the brief tour through to the historical and astronomical origins of timekeeping even in an era where men no longer believe that 24 hour days and rotations keep in step. Astronomy today is basically rudderless - an exercise in voodoo and bluffing created by academics and for academics while basic facts and enjoyable principles are ignored and even despised.
