Does Daniel 9:24 describe what Christ accomplished and fulfilled at Calvary?
Yes. Only Jesus could. Without blemish.
15 For this reason He is the Mediator
and Negotiator of a new covenant [that is, an entirely new agreement uniting God and man],
so that those who have been called [by God] may receive [the fulfillment of] the promised eternal inheritance, since a death has taken place [as the payment] which redeems them from the sins committed under the obsolete first covenant.
And was what He accomplished and fulfilled at Calvary only about the nation of Israel, or was it about the whole world?
Clearly the whole world.
Jn 3
16 “For God so [greatly] loved
and dearly prized
the world, that He [even] gave His [One and] only begotten Son, so that whoever believes
and trusts in Him [as Savior] shall not perish, but have eternal life.
17 For God did not send the Son into the world to judge
and condemn the world [that is, to initiate the final judgment of the world], but that the world might be saved through Him. 18 Whoever believes
and has decided to trust in Him [as personal Savior and Lord] is not judged [for this one, there is no judgment, no rejection, no condemnation]; but the one who does not believe [and has decided to reject Him as personal Savior and Lord] is judged already [that one has been convicted and sentenced],
because he has not believed and trusted in the name of the [One and] only begotten Son of God [the One who is truly unique, the only One of His kind, the One who alone can save him].
19 This is the judgment [that is, the cause for indictment, the test by which people are judged, the basis for the sentence]: the Light has come into the world, and people loved the darkness rather than the Light, for their deeds were evil. 20 For every wrongdoer hates the Light, and does not come to the Light [but shrinks from it] for fear that his [sinful, worthless] activities will be exposed
and condemned. 21 But whoever practices truth [and does what is right—morally, ethically, spiritually] comes to the Light, so that his works may be plainly shown to be what they are—accomplished in God [divinely prompted, done with God’s help, in dependence on Him].”
28 so Christ, having been offered once
and once for all to bear [as a burden] the sins of many,
will appear a second time [when he returns to earth], not to deal with sin, but to bring salvation to those who are eagerly and confidently waiting for Him.
Sin has been put away. What the world needs to do is repent before he comes again.

Act 17
30 Therefore God overlooked
and disregarded the
former ages of ignorance;
but now He commands all
people everywhere to repent [that is, to change their old way of thinking, to regret their past sins, and to seek God’s purpose for their lives], 31 because He has set a day when He will judge the
inhabited world in righteousness by a Man whom He has appointed
and destined for that task, and He has provided credible proof to everyone by raising Him from the dead.”
