1440 years. Christ arrived at the third Shekinah after the Flood. A shekinah is a time in the heavens when the planet Venus conjuncts with Mercury and appears as a blazing star in the heavens to watchers below. They did not realize it was two planets but thought it was a big star that was sent to herald an event. Curiously it did usually coincide with major events in Jewish history. A shekinah occurs each 480 years but on third time it has completed a cycle and shows against the same starry background as three time before so that is why the third of each shekinahs is so special. There must have been another about 1436 or so ( Christ was born in about 4 0r 5 BC)
