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).

Year (yr)
The average Gregorian calendar year of 365.2425 days (31,556,952 seconds). A common year has 365 days and a leap year 366.
A year is the Earth's trip around the Sun, but there are several versions. The tropical year, which tracks the seasons, is about 365.2422 days. The sidereal year, measured against the stars, is about 365.2564 days, roughly 20 minutes longer, because the Earth's axis precesses. Calendars must squeeze these into whole days, which is the origin of leap years. English year descends from Old English gear, while Latin annus, the source of annual, comes from a different root.
The Gregorian calendar, introduced by Pope Gregory XIII's bull of 24 February 1582, fixed the problem of Julian drift that had moved the March equinox away from 21 March and upset the date of Easter. Ten days were skipped, so Thursday 4 October was followed by Friday 15 October. Its rule of skipping leap days in century years not divisible by 400 gives a mean year of 365.2425 days, the value this site uses for the year. Britain and its empire switched in 1752 and Russia in 1918. Scientists write the year as a, with the Julian year fixed at 31,557,600 seconds.
1 year = 31,556,952 seconds (exactly).
