You meant 365 days of course,the term 'solar' is merely pretense in the absence of having a clear view of the equation between 1461 rotations on one side and 4 orbital circuits on the other hence the fundamental unit of timekeeping is a proportion like Pi,not as exact of course but good enough to posit 365 1/4 rotations for one orbital circuit as a derivative of the core observation of 1461 rotations in 4 years.
Nobody should be expected to explain that February 29th closes out 1461 rotations of the Earth that began March 1st 2008 more than once but if you are intent on believing it is the 1465th rotation in 1461 days then be my guest and believe that space is warped or time travel is possible along with it,I am not throwing good information after bad regardless of who's reputation is on the line.
You have just had your own reference system explained to you by the Egyptian astronomers of 2000 years ago in making the distinction between the seasonal return of the star Sirius and Flamsteed's ill considered return of Sirius in stellar circumpolar motion,by coincidence the same star the Egyptians used in referencing the orbital cycle of the Earth and not its daily rotational cycle.
The next time mathematicians decide to carve up astronomy so they can engage in thought experiments or experiments of any kind,be sure to check with an astronomer first,if another one can be found.
