2 obstetric calendars were made to find the gestational age starting from the month when the last menstruation began to the wished date or the date of the appointment, based on the number of days every month has. A simple and precise rule was also created to know the probable date of delivery according to the International Federation of Gynecoobstetrics. The accuracy and rapidity of every calculation, as well as the low cost for their mass application and their great usefulness were considered.
