Tenpō calendar facts for kids
The Tenpō calendar (Tenpō-reki) was a special type of calendar used in Japan. It was a lunisolar calendar, which means it used both the Moon's phases and the Sun's position to keep track of time. This calendar was created during the Tenpō era, which lasted from 1830 to 1844. It was an important calendar used in Japan during the later part of the Edo period.
History of the Tenpō Calendar
The Tenpō calendar system was designed by a clever Japanese astronomer and mathematician named Shibukawa Kagesuke. This calendar was very special because it was the very last traditional calendar system that Japanese experts created.
The Tenpō calendar was used for many years. However, things changed in 1872, during the Meiji period. Japan decided to start using the Western calendar, which is the calendar most of the world uses today. Because of this, the Tenpō calendar was no longer needed for official use.
