Kyoto's mountain cherries reached full bloom on April 14, 1207 — day 104 of the year. Of the 838 years on record, the 383rd earliest. From 812 to 1850 the average was April 15 (day 105.2). The 30 years to 1207 averaged day 106.5. 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.
