Why is the Olympics played only every 4 years?

because there are 4 gods in Greece

they use to celebrate

that is how Olympics was made

they use to celebrate the gods on separate years

but now they celebrate the gods together

so Olympics is every 4 years

The summer Olympics are held every 4 years, same with the winter, but they alternate, so that the summer Olympics is in 2000 and the winter Olympics is in 2002. Then that means the next summer Olympics is in 2004 and the next winter is in 2006.
