Why 000-179 ... and not 001-180??

Since 000 is not a real direction... (North is 360) ..., is there some
significant history why easterly/westerly cruising altitudes were chosen on
the basis of: 000-179 --- 180-359
as opposed to the more intuitive: 001-180 --- 181-360 ???

Don't know why it was set up this way, but it's always been a good
memory aid for me. Headings beginning with 0 remind me of O (the
letter "o") which makles me think "Odd thousands + 500"
