`:Meeus gives both the Julian date and the corresponding date/time which meet my criteria in a worked example: the new moon of February 1977 occurred at 2443192.65117 or 1977 February 18 3:37:41 TT (p.323). However, he refused to use the term ``Julian date``, stating that that meant a date in the Julian calendar, using instead Julian Ephemeris Days (JDE) (p.59). Instead of Ephemeris Time used from 1900 to 1983, Meeus noted that in 1984 both Barycentric Dynamical Time and Terrestrial Dynamical Time were implemented, but because the difference between them does not exceed 0.0017 seconds, he used a generic ``Dynamical Time`` (TD) (p.71). TDT was renamed TT in 1991. —       `
