No. When talking about years trimester and quarter is the same thing. Trimester means a three month period and since a year has twelve months a quarter is also three months.
Might be a language difference, as here a trimester is generally understood as a 4-month period, with 3 trimester forming a year. (2 semester, 3 trimester, 4 Quartals...)
