The 2300 Days of Daniel - Figure 3
The "Transgression of Desolation" is another term for "Abomination of Desolation." This is a point in time whereas the daily sacrifices and the trampling of the sanctuary are lengths of time.
The "Transgression" is that act, from mankind's standpoint, of idolatry against God, which brings desolation. The "Abomination" is that evaluation, from God's standpoint, of the transgression of mankind that results in desolation.
