how long after the asteroid hit did the dinosaurs dies. My question is how long did it take after the asteroid hit that the dinosaurs died?

This is difficult to determine as the fossil record deals in geologic time frames which are typically thousands of years. We do know that there was a mass extinction immediately after an iridium layer was deposited 65 million years ago, presumably as a result of the impact of the meteorite or asteroid near the Yucatan. Whether that extinction took a week or a thousand years would be mostly speculation, but one might suppose with reasonable certainty that the larger, more specialized animals such as the dinosaurs would have been among those least able to adapt the the suddenly and radically altered environment and would be the first to succumb.

What you are saying is mostly false. How could a asteroid kick up enough dust to blanket the Earth?
What really happened is this. The asteroid's friction caused it to burn all of the forests around it. The SMOKE was the thing that blocked sunlight. It took probably a few weeks because that is how long it would take for many large plants to die and for dinosaurs, who eat a lot, to die.
Also the smoke pollution would have helped the dieing process.
So I would estimate a good 2 or 3 weeks before most of the dinosaurs were dead.

your question assumes all the dinosaurs died immediately. i imagine there was more of a collapse of ecosystems caused by vast global changes, such as light exposure, water temperatures, atmospheric changes, and probably a major shift in just about every conceivable variable. however, not everything from the era died, and not everything that went extinct resulted from the immediate implications of an asteroid hitting earth

I wasn't there nor did I stay in a Holiday Inn last night....but, I would guesstimate it depends on the distance from the impact site. Those far away probably lasted weeks after the dust cloud circled the earth, while others lasted longer. Some didn't go extinct but were able to get by.

Many days and the big problem was that the dinosaurs required such a large amount to eat just to survive.
