I found Equinox days culculated by kholidays may be wrong. For example, kholidays says March 22th is Vernal Equinox Day in 2018, but actual Japanese Vernal Equinox Day is March 21th in 2018. I think Equinox Days should be kept. I also want to know how to hide automatically-calculated equinox days. I will send another patch later.
