Has the Mid-Autumn Festival ever been celebrated on the same day as the cold dew solar terms in history?

The autumnal equinox solar term is on September 23rd or 24th every year, and the Mid-Autumn Festival is on August15th of the lunar calendar every year.

The next solar term of the autumn equinox is the cold dew, which belongs to the autumn equinox before the arrival of the cold dew solar term. This year's Mid-Autumn Festival is before the cold dew solar term, so the Mid-Autumn Festival is in the autumnal equinox solar term.

The autumnal equinox is the sixteenth solar term in the twenty-four solar terms of the lunar calendar, usually on September 23rd or 24th every year. The climate in the south began to decline from this solar term. First, on this day, the sun reached the longitude of the Yellow River 180 degrees, and directly hit the equator of the earth. So a day is divided into 24 hours, each 12 hours: there is no extreme day and night phenomenon in the world.
