Hi,<br/><br/>I have heard the expression like these:<br/><br/>first quarter, second quarter, third quater (3Q). Also,<br/><br/>first half, second half.<br/><br/>Then do you say,<br/><br/>first third (sounds acceptable)<br/><br/>second third (sounds acceptable)<br/><br/>third third (sounds wrong)<br/><br/>?<br/><br/>Thank you,<br/><br/>M
