The indictment must state that the offense was committed on some particular day within the statute of limitations, although the precise day is not material; any day within the statute of limitations is sufficient.40 An indictment charging that the offense was committed "on or about" a certain day is too indefinite.41 So, an indictment which states an offense to have been committed on an impossible date is bad and may be quashed.42 If from the face of the indictment the offense is shown to have been barred by the statute of limitations, it may be quashed.43 In determining the sufficiency of an indictment the court will assume the date alleged in it is the proper date.44 But some courts hold the contrary, for the reason that the case may come within an exception contained in the statute, such as if the accused fled from justice.45
