In the West, we often refer to “the dog days of summer.” In 16th century England they were said to have run from July 7 to September 5, but were shortened to the term between July 19th and August 20th in 1660.

They are connected with the appearance of Sirius in the night sky in the Northern Hemisphere around July 19th. The mythologies of the Greeks and Romans connected the period with “heat, drought, thunderstorms, fever, mad dogs and bad luck.[wiki]”

The term refers to the hot and oppressive days of summer and would be suited to the period around Obon here in Japan.


西洋では盛夏はよく『the dog days of summer』として表現される。16世紀の英国ではその期間は77日~95日まで及んだが、1660年には719日~820日に短縮された。

719日頃の天狼星(シリウス )が北半球に見られる時期と関連されている。ギリシャやローマ神話にはその期間は「暑さ、干ばつ、激しい雷雨、発熱、狂犬病の犬と不運[wiki]」と関連付けられた。
