It takes three Saros cycles, known as an Exeligmos, for an eclipse to occur at approximately the same location on Earth. Each Saros cycle is about 18 years, 11 days, and 8 hours, and the extra 8 hours cause the eclipse to shift westward. After three cycles, the timing aligns closely enough for the eclipse to occur at a similar location.
