Is 清明节 actually Easter?
Both festivals revolve around the spring equinox. 清明节 falls 15 days after the spring equinox, whereas Easter falls on the first sunday after the first fullmoon after the spring equinox.

Christianity here just superimposed their own myth (the carpenter on the cross) onto the existing Jewish passover, and the Jews in turn just superimposed their myth (the exodus from Egypt) onto then existing premosaic traditions in West Asia.

清明节 is also a redevelopment of 寒食节, although these festivals are more original than any of the Easter traditions. In Taiwan, 清明节 has unfortunately been politicized to commemorate the death of the nationalist dictator 蒋介石.

Let’s just say that both festivals celebrate the coming of spring, that is the essence of it.
