Kanreki
Cycles of sixty years: A celebration of re-born
August 8th, 2024
Via Wikipedia: "The traditional lunisolar calendars in the Sinosphere (Chinese calendar, Japanese calendar, Korean calendar) observe sexagenary cycles: cycles of sixty years. Thus, living sixty years had special significance as one completed a full cycle. Some saw it as the start of a second lifetime, and thus as an opportunity to give up some responsibility and return to enjoying life as children do."
Via Iromegane: "60th birthday is one of the biggest birthdays in Japan and is called Kanreki (還暦) in Japanese. This kanji, 還 (kan) means circulate and 暦 (reki) is a calendar and we can understand it as years. So kanreki literary means, your years completed a circle, in other word, you come back to the same year as when you were born.
Still puzzled? This comes from the way ancient Japanese people counted the years. They didn´t use the Gregorian calendar but the lunar calendar and each year was counted with 12 different animals, which is called Junishi (十二支) ; Ne (子/ mouse), Ushi (牛/ cow), Tora (寅/ tiger), U (卯/ rabbit), Tatsu (辰/ dragon), Mi (巳/ snake), Uma (馬/ horse), Hitsuji (未/ sheep), Saru (申/ monkey), Tori (酉/ chicken), Inu (戌/ dog), I (亥/ hog). This is still kept in the modern Japanese life. By the way, this year, 2015 is a year of sheep and the next year 2016 is a year of monkey.
Wait, if there are 12 animals, when it circulate completely, it only takes 12 years and you should be 12 but not 60. Mathematically incorrect. Each year is combined with one of Jikkan (十干), which indicate time and space and there are, Kinoe (甲), Kinoto (乙), Hinoe (丙), Hinoto (丁), Tuchinoe (戊), Tsuchinoto (己), Kanoe (庚), Kanoto (辛), Mizunoe (壬), Mizunoto (癸). For example, this year is a year of sheep and with jikkan, it´s Kinoto Hitsuji (乙未).
The combinations are 60 in total and that is why kanreki makes sense as one circle. As the person completes whole 60 combinations, the 60th birthday is also a celebration of re-born. The person will start a new circle of life."
