The O-C curve of the very late type close binary (dM1e + dM1e) YY Geminorum is formed and analyzed based on all available times of minimum light. It is found that the orbital period shows a secular decrease with rate dP/dt = -1.08 × 10-8 days yr-1. There is weak evidence indicating that a small-ampl...
