What is the next solar term in the Millennium?

The next solar term of the Millennium is the autumnal equinox.

Bailu: On September 7th or 8th every year, due to the obvious southward shift of the direct point of the sun, the temperature drops rapidly and the weather is cool. Water vapor close to the ground at night forms white dew on vegetation, hence the name "white dew".

Autumnal equinox: On the 23rd or 24th of September every year, the direct sunlight point returns to the equator, forming equal length of day and night.
