Maksimal-kan Batu Permata dihubungkan dengan hari / planet.

The week is a division of time equal to seven days. We do not know exactly where it comes from, but the ancient Hebrews were among the first to use it. The book of Genesis in the Bible says that the world was created in six days and the seventh day, or Sabbath, was a day of rest and worship.
Ancient Egyptians named the days after planets, which they incorrectly believed included the sun and the moon. The seventh day was considered merely a day of rest and play. In ancient Rome, the days of the week were named after the sun, the moon, and the five planets then known. Each day was considered sacred to the Roman god associated with that planet. The days were known as Sun’s-day, Moon’s-day, Mars’-day, and so on. This system was used about the beginning of the Christian Era. The English names for the days Tuesday, Wednesday, Thursday, and Friday were derived from the names of Norse gods.
Most Latin-based languages connect each day of the week with one of the seven “planets” of the ancient times: Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn. French, for example, uses the following:
