A more thorough explanation:

Definition: Quarter can have two meanings:

1. In the law of war, it means to show mercy to a defeated enemy by sparing lives and accepting a surrender. For example, "The soldiers decided to give no quarter to the enemy."
2. It can also refer to a quarter section in land surveying. For example, "The farm was divided into four quarter sections."

Quarter day is another term related to quarter, which refers to a specific day in the year when rents and other payments are due.

Examples:

• During the battle, the general ordered his troops to give no quarter to the enemy soldiers.
• The land surveyor marked off the property into quarter sections.
• Rent is due on the quarter day, which falls on March 25th.

The first example illustrates the first definition of quarter, which is related to war and showing mercy to the enemy. The second example illustrates the second definition of quarter, which is related to land surveying and dividing land into sections. The third example illustrates the term quarter day, which is related to a specific day in the year when payments are due.
