In human reproduction process, analysing the birth interval is a crucial and important aspect. Mostly some of the authors show their keen interest in the study of birth intervals even in the modern era when age at marriage and education level is has increased up to a certain level which is quite satisfactory. For estimation of fertility parameters i.e. fecundability, researchers have shown keen interest in the interval between marriage and first conception since sixties under various set of assumptions consi3dering discrete as well as continuous probability distributions. Since the data of conception cannot be observed directly, thus, used the data of length of first birth and subtracted a fixed value of gestation period i.e. Nine months from the duration of first birth interval. In this paper an attempt has been made to estimate the gestation duration by adding a parameter for gestation period in the model. In this study 9.3 months gestation period is obtained as the most probable value, which is almost 282 days.
