Eh? Mercury is always in its orbit. It doesn't take breaks from going around the sun.

I'm saying how much of its orbit was completed on Oct 9th, 2006 since the last time it orbited the sun.

Well its orbit is 88 days. So subtract 88 days from Oct the 9th and there is your answer (if I understand you correctly)

Edit: I work out as - July 13th

Are you asking how many days from perihelion Mercury was on Oct 9th 2006? Some people define "start of orbit" as perihelion (closest to Sun), especially when using elliptical parameters, but there are other ways to define "start of orbit" too

yea

Maybe it starts at 12 on the dial.

That does not answer my question. How much of Mercury's orbit was completed? What day in its orbit was it in? day 20? day 50? day 80? One thing I know is that Mercury is in the Virgo constellation at this moment. and I can trace this back to 2006. But that still does not tell me where Mercury's orbit starts and ends. I really don't want to do the math to figure this out.
