Oligomenorrhea gap between 2 menstrual cycles is 35 days or more. That will be around 10-11 cycles per year.
One more definition is less than 8 cycles per year.

Take that 35d or more as 60d.
What if a lady had cycles every 36 days. She shd be oligomenorrhic according to definition. This will come to 10 cycles In an year
