24 maio 1968 ano - 1968.5.24: START of Truncated Julian Day Count [TJD]

Descrição:

"Truncated Julian Date, TJD, is a truncated form of MJD. The starting TJD point is midnight May 24, 1968 (Ahhh, I remember that night well...). Thus there are two formulae for calculating TJD. TJD = MJD - 40000, assuming you know the MJD. If you only know the JD, TJD = JD - 2440000.5. In both cases, MJD and TJD, it is generally used in integer form, representing the day only, not the day and time, though it is fully capable of both day and time unless expressed as an integer."
