It is usual for fieldworkers to devise tools or ways and means to obtain the utmost data possible and to arrange them for use. This paper is one of them and has two aims: (a) to introduce a dimensional awareness in field observation techniques employed in ethnographic work; and (b) to show how a socioeconomic calendar can be of some utility in social planning and programming. A socioeconomic calendar is an instrument for ordering cultural data according to the common Gregorian calendar and calibrating them with natural phenomena. I have not seen this utilized in ethnographic work, so this is the motivation for this short paper.
