LDS Mesoamerican scholars John L. Sorenson, John E. Clark, Brant
A. Gardner, and Mark Alan Wright have all discussed various ways Nephite years might
actually be 360-day tuns of the
Mesoamerican Long Count calendar.[1]
In his article on dating the death of Jesus Christ, ancient Near Eastern
archaeologist Jeffrey R. Chadwick disputed this suggestion. Chadwick asserted, “There is no
indication that the Maya thought of their tun count as a ‘year,’” and
that “[Michael D.] Coe does not refer to the tun as a ‘year’ anywhere in
his discussion of the Mayan calendar system.”[2]
Unfortunately, Chadwick has not done enough research on the
Mesoamerican Long Count. Coe himself does not call the tun a year, but several other scholars do. Mary Miller and Karl
Taube, for instance, explained the Long Count as follows:
Periods of time were counted by days, periods of 20 days (the
uinal), years—sometimes called “computing years by archaeologists”—of 360
days (the tun), 20-year periods of 360 days each (the katun), and 400-year periods (the baktun).[3]
Joel W. Palka said the Long Count “is calculated by
multiplying a certain number by five different periods: baktun, or 400 years
(360 days), katun, or 20 years, tun, or a year, uinal, or a month (20 days), and kin, or a day.”[4]
Kaylee Spencer and Linnea H. Wren use the heading “Winal and Tun: Month and
Year,” to title the section of their paper on those time periods in the Long
Count system.[5]
The use of 360 days deliberately broke from the standard
pattern of the Long Count in order to better approximate a year, according to
Anthony F. Aveni.
To reckon deep time, the Maya created the longest
Mesoamerican calendar cycle by multiplying the basic unit of twenty to the
fifth order, the exception being the multiplication of the 20-day count by 18
to form a cycle of 360 days, or one tun,
which approximated the year.[6]

Lars Kirkhusmo Pharo similarly explained that the 360-day
cycle in the Long Count “was the fundamental unit intended to approximate the
solar or vague year of 365 days.”[7]
The Maya even used the same
word for both the 360-day period and the 365-day solar year, according to
Michael D. Coe and Stephen Houston. After describing the “‘Vague Year or Ha’b of 365 days,” they discussed the
Long Count system and noted, “in a switch sure to confuse modern readers, the
tun was really called ha’b!”[8] Pharo
presented the Long Count system “with Yucatec designations in parenthesis” as
follows:
Pik
(Bak’tun): 144,000 days
Winikhaab
(K’atun): 7,200 days
Haab
(Tun): 360 days
Winal/Winik:
20 days
K’in: 1 day[9]
Notice, again, that
haab is equivalent to tun. In a footnote, Pharo mentioned of the “haab
of 360 days,” and also explained, “Tun is the Yucatec word for haab,
which is a Yucatec designation for a year of 365 days.”[10]
Today, it is a scholarly convention to use haab for the 365-day year and
tun for the 360-day year (I assume to avoid confusion), but in
pre-Columbian times, both terms were used for both the 365-day and
360-day periods—one (haab or h’ab) being the lowland Maya
term, the other (tun) being the Yucatec term.
So for all intents
and purposes, the Maya did call the 360-day period a “year.” Of course,
this does not mean that the Book of Mormon year was the 360-day tun, but
it does illustrate that Chadwick’s reasons for rejecting that possibility are
not well founded.
