IEYASU (1542-1616) VERSUS IEYASU (1543-1616):CALENDRICAL CONVERSION TABLESFOR THE 16th AND 17th CENTURIES

José Miguel Pinto dos SantosHiroshima University

Disputes concerning the time or place of occurrence of a certain eventare not uncommon among historians. One example that naturally comes tomind in the history of the relations between Portugal and Japan in thesixteenth century is the argument about the date of arrival of the firstPortuguese in Japan 1. These controversies are not, for the most part, futile. It is not only good sense to try to ascertain with the maximum possiblecertainty the background of a certain episode before attempting to offerhigher interpretations on its meaningfulness, but from these discussionsusually emerges a deeper understanding of the circumstances surroundingthe event.

There is no such a dispute concerning the date of birth of TokugawaIeyasu No serious doubt is on record that he was born on the 26th

day of the Twelfth Month of the 11th year of Tembun . However, the carefulreader of Western periodicals or collective works with articles pertaining tothe history of Japan of the 16th and 17th centuries might be forgiven if hethought that one such quibble was going on between two scholarly factions.He would notice in his reading that although the majority of authors wouldindicate 1542 as the year when Ieyasu first saw light, not a few others wouldoffer 1543 instead.

It is beyond the purpose of this short note to offer a careful statisticalanalysis of the relative frequency with which 1542 and 1543 are chosenamong scholarly writers for the first item in the date duplet following theopening reference to Ieyasu in their articles. Concerning fact, frequency ofopinion does not make right. But to substantiate the observation made that

1 This was one of the longest polemics in this field. Before been closed in favor of 1543 by GeorgSchurhammer, “O descobrimento do Japão pelos Portugueses no ano de 1543”, Anais da Aca-demia Portuguesa de História, Ser. 2, 1 (Lisbon, 1946), pp. 1-172, another strongly advocatedpossibility was 1542, a date first advanced by António Galvão (see Antonie Galvano, The Discov-eries of the World from their first originall vnto the yeere of our Lord 1555, Londini, Impensis G. Bishop, 1601, p. 92).

there is a disparity between authors regarding the year attributed to the birthof the first Tokugawa, in Table I is presented a sample of thirty seven refer-ence works in eight languages that were inspected in their entries for Toku-gawa Ieyasu about the date of his birth.

Nineteen of the works listed, or about half, are Japanese. While one ofthese nineteen does not give a Western date for Ieyasu’s birth, sixteen choose1542, and just two opted for 1543. Six of these Japanese works specialize inhistory. In this category five prefer 1542 against one that selected 1543. Of theeighteen non-Japanese works in the table, thirteen give 1542 against five thatpresent 1543. Of the five that record 1543, one is Chinese, two are English(one specializing on Japan), one is French and another is German 2.

The widespread use of 1542 for Ieyasu’s birth date is, to say the least,unfortunate. It stems not from any doubt concerning when an event tookplace, but from an inappropriate correspondence that is usually madebetween the years in the Japanese traditional luni-solar calendar and theyears in Christian solar calendar 3. Although years in the Japanese luni-solarcalendar were not coterminous with the Julian and Gregorian calendars, aninaccurate correspondence between the Japanese luni-solar year and theWestern year has become common where, for example, Tembun 11 is identi-fied with 1542. To be sure, most days of Tembun 11 fell in 1542. The problemis that not all days of Tembun 11 fell in 1542, and thus the automatic identifi-cation made between the two years is inaccurate. 1542 has a precise meaningthat should be preserved. It indicates those days between its beginning inJanuary 1st (e.g., the 15th day of the Twelfth Month of the 10th year of Tembunin the Japanese traditional calendar) and its end in December 31st (e.g., the25th day of Eleventh Month of the 11th year of Tembun) to the exclusion of allother days. Likewise Tembun 11 has a precise meaning that should not betampered with. It indicates those days between the first day of its Shógatsu(e.g., January 16, 1542) and the last day of its last month (the 29th day of the

Twelfth Month 4, or February 3, 1543). Thus, although Ieyasu was born inTembun 11, he was not born in 1542 but in1543.

There are several possible causes to the prevalence of this undue corre-spondence between years in the two calendars. One might be the fact that theJapanese calendar has been coterminous with the Western one since 1873,when Japan adopted the Gregorian calendar (except for the use of nengóoooo, where years are counted according to a system of short duration eras).Thus an exact correspondence has existed for the beginning and end of theyears in the two calendars for about 130 years. Under these circumstancesand under the weight of custom it has become easy to make the assumptionthat even before 1873 a certain nengó year was coterminous with a Westernyear. Unfortunately this easy assumption has become all to common. Anotherreason might be the scant number of history textbooks, manuals and otherreference works, in Japanese and in Western languages, that acknowledgesthe no-coterminousness of years between the two calendars. On the contrary,the assumption of coterminousness is widespread both in Japanese and non-Japanese history publications and specially glaring in their chronologicaltables and time lines. The result is a low awareness to this problem. Finallyalthough there are many conversion tables for the two calendars 5, they mightnot be easily accessible, especially outside Japan, or be easily usable, particu-larly by those who have less than good knowledge of written Japanese 6.

To lessen this problem and having particularly in mind the students of thehistory of the Japanese-Portuguese relations, in Table 2 an instrument for theconversion of dates between the traditional Japanese calendar and the Julian

and Gregorian Calendars is presented. Although the first period of contactbetween the two countries started in the 1540s and ended in the 1640s, this tablecovers the whole of the sixteenth and seventeenth centuries. This extendedperiod was chosen because many people active in the 1550s were born andeducated early in the 16th century, and because many of those who had memo-ries of the 1620s and 1630s wrote and died later in the 17th century.

Table II is designed in the following way. Each line represents a year andeach column represents a month in the Japanese calendar. In the intersectionof a line with a column is given the Western date of the first day of the corre-sponding Japanese month. Western dates are given in either year/month/dayor month/day format. The first format is used always for the first month of aJapanese year and for intercalary months. It is also used when the first day ofmonth falls in a different Western year than the first day of the previousmonth fell. To simplify and save space the second format is used in all othercases. Thus, for example, it can be observed that the first day of the firstmonth of the first year of Kóji oooo fell in January 23, 1555, the first day of theSecond Month of the same year fell in February 22, 1555, and so on. Kóji 1had an intercalary month, in this case an Intercalary Tenth Month, what isindicated in the intercalary month column, the rightmost column, by an (10).The first day of this month fell on November 14, 1555. The previous day,November 13, 1555, was the twenty ninth day of the Tenth Month. We knowthis because an Intercalary Tenth Month follows a Tenth Month and we knowthat the Tenth Month of Kóji 1 had 29 days because the type is not bold. Boldtype indicates that a month had 30 days. This was the case of the IntercalaryTenth Month of Kóji 1 and the month that followed it, the Eleventh Month.October 4, 1582 (18th day of the Ninth Month of Tenshó 10) was the last day inthe Julian Calendar and was followed by the first day of the GregorianCalendar, October 15, 1582 (19th day of the Ninth Month of Tenshó 10).Western dates in italic indicate that the conversion is made into the JulianCalendar; otherwise the conversion is made to the Gregorian Calendar. Forastronomical calculations it is usually more convenient to use the GregorianCalendar. Adding ten days to the Julian date we obtain the “equivalent”Gregorian date. Finally it should be noted that name eras (or nengó) could bechanged anytime during the year. In Table II we follow the usual practice ofattributing the entire year in which a new era began to the first year of thenew era. However, Japanese documents written during the last year of an era,just before a new one was proclaimed, will be dated after that era.

From the discussion above it should be obvious how to convert datesfrom the Japanese calendar to the Western one. Conversion of dates from theWestern calendar to the Japanese calendar is slightly less convenient. Forexample, we know that Francis Xavier reached to Kagoshima in August 15,

Ieyasu (1542-1616) Versus Ieyasu (1543-1616) 13

1549. To obtain the Japanese date, we first look for 1549 in the column corre-sponding to the first Japanese month. Having located this, one can do one oftwo things. We can move along this line until we find 08/23 in the columncorresponding to the Eighth Month. As we know that the Eight Month beganin August 23, August 15 must be the eighth day counting backwards from thelast day (inclusive) of the Seventh Month. As the Seventh Month had 29 days,Xavier arrived in Kagoshima the 22nd of the Seventh Month of Tembun 18.Another way would be to count the number of days between July 25 (when theSeventh Month began) and August 15: there are 22 days, inclusive of July 25,so we arrive again to the conclusion that Xavier arrived in Kagoshima the22nd of the Seventh Month.

This table is presented here having foremost in mind those historians whocannot read Japanese. Thus some other information that is normal in tablespublished in Japanese, such as sexagenary cycles, is omitted. Though this infor-mation may be important in certain cases for dating Japanese events and docu-ments the chances are that it will of no use for our target readers. It is expectedthat this table will be of use in two main cases. First, it may be used to convertdates in the Japanese calendar that may be found in modern translations ofJapanese primary sources. Considerable amount of Japanese primary sourceshave been translated into Western languages, usually giving the date in theJapanese calendar without conversion into the Western date 7. Second, it canalso be employed to convert dates given in the Japanese calendrical systemappearing in European primary sources of the sixteenth and seventeenthcenturies. For example, in a letter written from Japan in 1555 we can read:

“Auerá quarto dias que nos escreueo que tinha feito a casa noua, &Lourenço escreueo que ate 27. da lüa de Iunho andáraõ a fazer hüacasa de oito braças & mea de comprido, & seis de largo. Começáraõa dizer missa nella a 28. da lüa de Iunho.” 8

It is clear that dates mentioned here are not June 27 and 28. Making theobvious assumption that lüa de Iunho stands for the Sixth Month in theJapanese traditional calendar we have that these dates are probably the 27th

and 28th of the Sixth Month in 1555. Making use of Table II it can easily befound that these days are July 15 and 16, 1555.

Abstract

This note argues that the one to one correspondence that exists between thedates in the Japanese traditional calendar and those in the Julian and Gregoriancalendars should be carefully preserved. Unfortunately this correspondence is notalways respected. The birth date of Tokugawa Ieyasu is presented as an example of theimprecise conversion that is often made between those calendars. To help those whowish to convert dates between the Japanese and Western calendars we publish asimplified conversion table for the 16th and 17th centuries.

Resumo

Este artigo defende que a correspondência biunívoca entre o calendário tradi-cional japonês e os calendários Juliano e Gregoriano deve ser cuidadosamente preser-vada. Infelizmente esta correspondência nem sempre é respeitada. É apresentadacomo exemplo de conversão imprecisa, que é frequentemente feita entre o calendáriojaponês e os ocidentais, a data de nascimento de Tokugawa Ieyasu. Para ajudaraqueles que pretendam efectuar conversão de datas entre os calendários referidosapresentamos uma tabela de conversão para os séculos XVI e XVII.
