The Japanese Calendar

Since ancient times, calendars have been indispensable for knowing the changes of days, months and seasons. Every era has various types of calendars used in the daily life of the people, and some were particularly enjoyed for their special features. In this context, old calendars contain highly interesting materials reflecting the transition in life-style and culture down through the ages.

This, then, traces the history of the Japanese calendar based on the National Diet Library's calendar collection, with special focus on the Daisho-reki calendar consisting of months, some with 30 days, others with 29, which was used in the Edo period (1603 to 1867). It also includes notes on how to better appreciate it.
