Days to Kin (Maya) (d to kin)

1 day equals 1 kin (Maya) exactly.

1 day = 1 kin (Maya)

How to convert days to kin (Maya)

To convert days to kin (Maya), multiply the number of days by 1. This factor is exact. To go the other way, multiply kin (Maya) by 1.

kin (Maya) = days × 1

Example: 10 days = 10 kin (Maya).

Months and years are not constant. This site uses the average Gregorian year of 365.2425 days, so one 'year' converts to 365.2425 days, not 365; use 'common year' for exactly 365 days.

About these units

Day (d)

Metric (SI)Current unit

24 hours or 86,400 seconds. The mean solar day; the actual rotation of the Earth is about 4 minutes shorter (see sidereal day).

Old English dæg is the root of our day, with close cousins in German Tag, Dutch dag and Icelandic dagur, all descending from Proto-Germanic dagaz. It is the oldest unit here, because the cycle of light and dark needs no instrument. Yet the day we count is a constructed average: the actual interval from one noon to the next varies through the year by up to about 7.9 seconds, because Earth's orbit is elliptical and its axis is tilted.

Astronomers smooth this out with a fictitious mean Sun, giving the mean solar day, and the day in the SI sense is fixed at exactly 86,400 seconds. Reality has drifted slightly: the mean solar day has recently averaged about 86,400.002 seconds, and tidal drag from the Moon is lengthening it by about 2 milliseconds per century. That is why 27 leap seconds were added to UTC between 1972 and 2022. One rotation measured against the distant stars is shorter, about 23 hours 56 minutes 4.09 seconds, and a year contains one more of these sidereal days than solar days.

1 day = 86,400 seconds (exactly).

Kin (Maya) (kin)

MayaHistorical unit (no longer in standard use)

One day, the basic unit of the Maya Long Count calendar.

In Mayan languages the word kʼin also means sun, and as a calendar term it names a single day. It is the smallest unit counted in the Long Count, the Maya system for numbering days from a fixed starting point, and it normally appears as the last position in a written date.

Inscriptions carved on stone monuments open with an Initial Series that lists the larger cycles first and ends with the kin count, a number from 0 to 19. Reaching 20 kin rolls the count over into the next unit, the winal. Because the kin is simply one day, no uncertainty attaches to its size: it matches the modern 86,400 second day used here, even though the Maya reckoned days from their own observations and not by clock time. Scholars still debate how Long Count dates line up with European ones, but that affects the date assigned to a day, not its length.

1 kin (Maya) = 86,400 seconds (exactly).
