Daniel 12: 11 - 12: And from the time that the daily sacrifice shall be taken away, and the abomination that maketh desolate set up, there shall be a thousand two hundred and ninety days. Blessed is he that waiteth, and cometh to the thousand three hundred and five and thirty days.
The prophecy of Daniel 12 has a threefold fulfilment.
1290 days (King Antiochus Epiphanes of Syria desecrated the temple till Judas Maccabeus restored the temple worship) + 45 days (Antiochus Epiphanes died) = 1335 days.
1290 days (the Romans besieged Jerusalem which began in A.D. 66 till the temple was destroyed in A.D. 70) + 45 days (the siege ended and the Romans withdrew) = 1335 days.
1260 days (the Tribulation) + 30 days (Armageddon) = 1290 days + 45 days (the Millennium is ushered in) = 1335 days.
