accusative aynı the month (as the object) aylanı the months (as the object) a specific, known object — whom or what
dative ayğa to the month aylağa to the months direction or recipient — to where, to whom
locative ayda at / in the month aylada at / in the months where it is; also having — mende bar, "I have it"

our ayıbız our month aylarıbız our months
you all's ayığız you all's month aylarığız you all's months

The overlap in the last rows is real, not a mistake: ayları can mean "his / her months", "their month", or "their months" — context decides.
