converting between calendar dates and Julian days

[cdeaglejr]

This HP PPL program can be used to convert between calendar dates and Julian days. With this software a UTC calendar date and time can be converted to the corresponding Julian days on the UTC (universal coordinated time; subroutine julian) , TDB (barycentric dynamical time; subroutine utc2tdb) and TDT (terrestrial dynamical time; subroutine utc2tdt) time systems. A TDB Julian day can be converted to a UTC calendar date and time using the tdb2utc subroutine.

The software and brief documentation for this program can be downloaded from
