Paul writes about the qualities of love in 1 Corinthians 13, which is often called "the love chapter."
The Aztec have 13 days in their week, just like the Maya. They are numbers from 1 thru 13. The Spanish called it a Trecena (means 13). It is not called a week because a week means 7, just like 10 days is a decade. The Aztecs also have 20 day names which always match a cycle in the 360-day Mayan Long Count, like 18 months that each contain 20 days and so are always the same day names (because the 5 days are not added to make 365 days). The 18 cycles of these 20 day names will always fall on the same month and day in this 360-day cycle.
