The seventy sevens in Daniel 9:24 refer to years. 483 of the 490 years have already passed. The last seven years will be the tribulation period. The latter 3-1/2 years of the seven are referred to as the “great tribulation” and “the time of Jacob’s trouble”.
I may be wrong. I am not a prophet. I am just trying to fit all of the pieces in such a way that they fit prophetic scripture without contradictions.
Please bookmark the link I posted and refer to it in September.
