What is the difference between Olympics and Olympiads?

Answer 1

An Olympiad is the period between Olympic games. It amounts to 4 years and was used by the Greeks for dating events, so since the Greeks believed the Olympic games began in the year we call 776 B.C., the second Olympiad should be 772-768. Greeks also used tenures of important secular or religious officials to keep track of time.

The adjective Olympic refers, as indicated, to the Olympic Games that were held not on Mt. Olympus, but near the opposite end of Greece, in Olympus (aka Olympos or Olympia), a district in Elis on the west side of the Peloponnese (Peloponnesus).
