About these units
Winal (winal)
20 days, the Maya 'month' of the Long Count.
A winal, also spelled uinal, is a block of 20 days and the second-smallest step in the Maya Long Count. It is often likened to a month, though it has nothing to do with the moon. Twenty kʼin fill one winal, which matches the 20 named days that cycle through the Maya sacred calendar and the 20-day months of the civil year.
On monuments the winal is the fourth number in a Long Count date, ahead of the kin. Its count runs from 0 to 17 and not to 19, because 18 winals make one tun of 360 days. This is the point where the otherwise base-20 system departs from pure powers of twenty. One carved example is a full-figure winal sign on Stela D at Copan.
At 20 days, a winal equals 1,728,000 seconds and is a little under three weeks. No modern calendar unit corresponds to it closely, and it is an exact count of days with no ambiguity about its size.
1 winal = 1,728,000 seconds (exactly).

Week (wk)
Seven days. The seven-day week comes from the ancient Near East and is nearly universal in the modern calendar.
Nothing in the sky produces a seven-day cycle, which makes the week a human invention with a contested pedigree. Babylonians marked the 7th, 14th, 21st and 28th of the lunar month as special, but that was not a continuous cycle. A continuous seven-day cycle tied to the Sabbath is attested in Judaism by the 6th century BC at the latest, and scholars disagree on whether it was borrowed from Babylon or developed independently. The Romans later used a week named for the Sun, the Moon and the five visible planets, and in AD 321 Emperor Constantine decreed it across the empire.
A week is seven days, or 604,800 seconds, and it divides evenly into neither months nor years, which is why calendars shift against it. The ISO 8601 standard starts each week on Monday and assigns week 1 to the week containing the year's first Thursday, so some years have a week 53. Other societies used different lengths: Rome had an eight-day market cycle, and revolutionary France used a ten-day week from 1793 to 1802. The English word comes from Old English wice, meaning a turn or succession.
1 week = 604,800 seconds (exactly).
