Wait a minute, wait a minute! Let us gather all information about the dates again, just to be sure.

This chapter shows that the second year of the LMC seniors started in April 2008. Therefore, the first started in 2007 and the third starts in 2009, so that they graduate in March 2010. In chapter 11 of the fourth volume, a sign tells us "2010 school year J...Women's University Entrance Examination". So the time frame is clear. They visit High School between 2007 and 2010 and then they start visiting the university since 2010.

Now about the birthdays: All four members are said to be 15 in their first year already. Since only Mio's birthday happens before April (where they started High School), everybody else would be too young to become highschool students in 2007 alongside Mio. So the birthdays of Yui, Ritsu and Mugi have to be in 1991 and Mio was born in 1992. That way, everybody is 15 in April 2007 and it also matches when Mio states that she is 17 during her first half of her third High School year (episode 7, season 2).
