modified Julian date (MJD) gâhdâd-e žulian-e vâtarzidé Fr.: date julienne modifiée A modification of the Julian Date, representing the number of days that have elapsed since midnight (instead of noon) at the beginning of Wednesday November 17, 1858. MJD = JD - 2,400,000.5 The reason for adopting that date is the fact that the Julian Day 2,400,000 just happens to be November 17, 1858. → modify; → Julian date. |
