Green Day

Some days run longer than the others,
And some even stretch for months,
Some days are shorter than an hour,
And end abruptly, leaving the table
With empty plates and several silver coins,

A green day is a light day,
It is neither short nor too long,
It is populated by walking trees and ringing dry grasses,
And in its bosom it has a small yellow bird.

The answer to this question lies in the physiology of wood formation.

In 2012 scientist Fusa Miyake announced the detection of high levels of the isotopes Carbon-14 and Beryllium-10 in tree rings formed in 775 CE, suggesting that a burst of radiation struck the Earth in the year 774 or 775. These isotopes form when radiation from space collides with nitrogen atoms, which then decay into these heavier forms of carbon and beryllium.
