365.256363, nearly.


Light year/day/second is a distance unit.
Year/day is a time unit.

Year in days is transcendental number like #pi#and cannot be expressed in exactitude, like a rational number.

I have given 9-sd approximation to sidereal year in days of 86400 seconds.

Sidereal year is the Earth's orbit period around the star Sun, with respect to the configuration of seemingly stationary stars.

#365.25# days approximately


Remember that,a light year is the distance travelled by light in one year.

And we know that

#1# year=#365.25# days

And thats the logic!
