## おきに vs ごとに

The way the intervals are counted between these two grammar structure is different.
* おきに refers to what is _inside_ the interval.
* ごとに refers to the interval _per se_.

> １日==おきに== =２日==ごとに== = every other day = every second day
> ●○●○●○●
>
> ２日==おきに== =３日==ごとに== (every three days = every third day)  
> ●○○●○○●○○●
