See:

for a table giving various features of the previous 7 Buddhas. The Direct answer to your question is that Kassapa and our Buddha were both born in this kappa, that is, world-cycle, or aeon. The kappa consists of a period of evolution, a period of stasis, a period of devolution and a period of stasis. This current period is the period of devolution (as if anyone had to tell you). It is not clear, but it is likely that Kassapa was born in the period of Evolution.

The kappa is described as: 10,395,902,500 years: 103,959,025 sesame seeds removed from a Magadhan Karika one at a time every hundred years (see Magadha Karika)
