Days of each rokuyō

Spring equinox date, 1951–2050

Computed from the JPL DE421 ephemeris with Skyfield, in Japan Standard Time. The lunisolar dates follow the traditional Tenpō rules for reference only (the leap month around 2033 is disputed). Rokuyō and the sexagenary cycle are calendar customs, not predictions.
