Abstract

A calendar date monitoring system particularly effective for monitoring pregnancy and other medical conditions is disclosed. The system includes a substantially flat calendar strip, which includes a first set of indicia arranged longitudinally on the calendar strip to define calendar days and months. A substantially flat interval strip includes a second set of indicia arranged longitudinally,on the interval strip to define predetermined time intervals. The second set of indicia include a first guide mark formed proximate one end of the interval strip, a second guide mark formed proximate the opposite end of the interval strip and a plurality of intermediate marks arranged between the first and second guide marks. The calendar strip and the interval strip are held in a longitudinally juxtaposed condition such that the first and second guide marks are aligned with selected indicia representing first and second dates on the calendar strip and the intermediate marks are aligned with indicia representing corresponding intermediate dates on the calendar strip.
