The d parameter is a double-precision floating-point number that represents a date as the number of days before or after the base date, midnight, 30 December 1899. The sign and integral part of d encode the date as a positive or negative day displacement from 30 December 1899, and the absolute value of the fractional part of d encodes the time of day as a fraction of a day displacement from midnight. d must be a value between negative 657435.0 through positive 2958465.99999999 .
Note that because of the way dates are encoded, there are two ways of representing any time of day on 30 December 1899. For example, -0.5 and 0.5 both mean noon on 30 December 1899 because a day displacement of plus or minus zero days from the base date is still the base date, and a half day displacement from midnight is noon.
