Which month is NOT included in the quarterly meeting schedule?

The quarter meeting schedule typically divides the year into four segments, each lasting three months. The first quarter consists of January, February, and March; the second quarter includes April, May, and June; the third quarter encompasses July, August, and September; and the fourth quarter features October, November, and December.

In this context, August falls within the third quarter, making it a part of the quarterly meeting schedule. The other months—March, June, and December—are all included in their respective quarters. Therefore, August is the only month listed that does not complete a full quarter that is traditionally accounted for in quarterly meetings, establishing it as the correct answer.
