Is there a Jewish tradition according to which each creative day was 7000 years?

Question

I remember hearing (long ago, so it could be that I remember wrong) that, according to a Jewish tradition, the last day of creation (Gods day or rest) is 7000 years long and that consequently the other 6 days (since they were the same length) would also be 7000 years long.

Is it correct that this type of tradition exists?

I don't know if this is a tradition, but there are those who interpret the verse in Psalms "For a thousand years in your eyes is like a passing day" (loose translation) to mean that when God speaks about days in the Creation story they are actually referring to 1,000 year eons.
