ABSTRACT
Pollen calendars are very useful for practising allergologists for the diagnosis and treatment of allergy in patients. The compilation of pollen calendars is the ultimate aim of aerobiologists. Like the U.S.A., in Japan there are basically three pollen seasons based on the habit of their plant sources: the tree pollen season from March-May; the grass pollen season from May-July and the weed pollen season from August-October. The pollen calendar of Melbourne shows the precise seasonal progression of pollen types from tree pollen in winter, grasses in spring and herbs and weeds in summer. Pollen calendars are generally useful in identifying allergies against particular airborne pollen types. In 1988, the Scottish centre for pollen studies compiled a pollen calendar based on 10-year review of pollen data. The calendar is published in the form of a colourful leaflet.
