Considering that the changes will focus, before any further considerations, in the calendar value and, only later, in the intensity, and knowing that Mozambique is one of the few Africans countries, which saw the re-birth of its nuptial calendar, we will focus, precisely, in the analysis of both phenomena calendar.

Keywords: Mozambique, fertility, nuptiality, calendar.
