Kyoto's mountain cherries reached full bloom on April 22, 1860 — day 113 of the year. Of the 838 years on record, the 63rd latest. From 812 to 1850 the average was April 15 (day 105.2). The 30 years to 1860 averaged day 107.1. Before modern weather records, the date comes from diaries and chronicles of flower-viewing parties at the imperial court, temples and shrines, gathered by Yasuyuki Aono.
