The existence of periodic solutions for the evolution equation

$ y'(t)+Ay(t)\ni F(t,y(t)) $

is investigated under considerably simple assumptions on $A$ and $F$. Here $X$ is a Banach space, the operator $A$ is $m$-accretive, $-A$ generates a compact semigroup, and $F$ is a Caratheodory mapping. Two examples concerning nonlinear parabolic equations are presented.
