did you know that the earth rotates at different speeds depending on the time of year?

One Earth day is about 24 hours long. Over the course of a year, the length of a day normally changes gradually by one millisecond. It increases in the winter, when the Earth rotates more slowly, and decreases in the summer, Gross has said in the past.

so my question is this - summer and winter *where*? if we are talking about 'earth', it's one of the other somewhere.
