Since 'munafuda's (dedication boards) are usually written at the time of putting up the ridge-beam of holy buildings. 'joto tatematsuru' (we dedicate this building in deep reverence) might be the most appropriate description. In actuality, however, this description constitutes only few percentage. According to these munafudas, these percentages show that the peak of the constructions was under way March and Spring, and August and September. But since the dates were written at the time of dedicating the building, we must assume that the construction works were already under way in spring, or further back in winter and summer, sometime during the off-season on the farm; that is, after the harvest and before the rice-planting time. In this conection, 'Daisho-tekagami' mentions, "January, July, October, November, and December are auspicious months for building a pole of the sate" ; meaning that the three months in winter except January and July correspond to the slack season on the farm when more helping hands are available.
