About this mark

Is 6 months the same as 180 days?

Almost never exactly. Six calendar months are 181 to 184 days. 180 days is its own row.

What if I quit on the 31st?

The anniversary uses the last valid day of the month six months later. 31 August plus six months is 28 February, or 29 February in a leap year.
