The first float returned gives the date, while the second float provides an additional offset for the particular hour, minute, and second of that date. Because the second float is much smaller in magnitude it can, unlike the first float, be accurate down to very small fractions of a second. >>> jd, fr = jday(2020, 2, 11, 13, 57, 0) >>> jd 2458890.5 >>> fr 0.58125 Note that the first float, which gives the moment of midnight that commences the given calendar date, always carries the fraction ``.5`` because Julian dates begin and end at noon. This made Julian dates more convenient for astronomers in Europe, by making the whole night belong to a single Julian date. This function is a simple translation to Python of the C++ routine ``jday()`` in Vallado's ``SGP4.cpp``. gv@ g(@g?g?ig"@gB:AN@g @@)yearmondayhrminutesecjdfrs R/home/cursorai/projects/iching/venv/lib/python3.12/site-packages/sgp4/functions.pyjdayrs2 $, qT)* +d 2c 9 : Ci#o      B  V +w 6B r6McT|dz}|r t||}t|d\}}|r t||}t|}t|d\}}t|d\}}|dzdk(xs|dzdk(xr|dzdk7}t||\}} |d k(rd }| d z } || t|t||fS) aConvert a float point number of days into the year into date and time.
