A more thorough explanation:

EVENINGS

Evenings in history referred to the delivery of a gratuity to a customary tenant at night. This gratuity was given in the form of a portion of the crop that the tenant had cut, mowed, or reaped for the lord.

For example, if a tenant had harvested a field of wheat, they would give a portion of that wheat to the lord as a form of payment for the land they were using. This payment was made in the evening or at night, hence the term "evenings."

Another example would be if a tenant had cut a field of grass for hay. They would give a portion of that hay to the lord as payment for the land they were using. This payment would also be made in the evening or at night.

The examples illustrate how evenings were a form of payment for the use of land. The tenant would give a portion of the crop they had harvested to the lord as payment for the land they were using. This was a common practice in medieval times and was a way for lords to maintain control over their land and ensure that they received payment for its use.
