The cold winter is coming to an end, and the warm spring will arrive soon. There must be people who started planning for cherry blossom viewing. It is very useful that recently you can search famous spots for cherry blossoms, to begin with, on internet or by some other ways, and you can check the status of blooming of cherry blossoms in some extent. For this time, I would like to introduce you to some trivia of cherry blossoms. Knowing such trivia, I suppose you can spend more fruitful time in cherry blossom viewing than viewing them aimlessly. 1. You can calculate the timing of blooming Although rough timings for blooming are often announced by region over TV or Internet, because the timings of blooming change, earlier or later, due to weather conditions, the timing of blooming is not always matching to that of announced. Though having said that, you still like to see the flowers on the timing of blooming. For that reason, I would like to recommend the calculation method of "a cherry blossom blooms on the day that excesses over 600 degrees Celsius of accumulated numbers of the highest temperature after February". It is said that the day that excesses 600 degrees Celsius by adding (the highest temperature of Feb/1) + (the highest temperature of Feb/2) + (the highest temperature of Feb/3) +... is about the timing of blooming. It takes about one week from blooming till in full bloom. Knowing this calculation method, you can calculate the status of cherry blossoms of each region by yourself. 2.
