Entering Japanese Emperor Year dates
You can enter Japanese Emperor Year (Wareki) dates in date fields. FileMaker Pro converts the Emperor Year to a Western Gregorian (Seireki) year and saves it internally in the format specified by the file. The display format of the date—Western or Japanese—depends on the date field format. There are two ways to enter Japanese Emperor Year dates:
 •
Era abbreviation: Enter the date in the format era letterY/M/D, where era letter designates the era (see the table below for a list of valid era letters), followed by the year, month, and day. For example,“M1/12/30” is converted to “1868/12/30” (M1 = the 1st year of Meiji, or 1868). Similarly, “T1/12/30” becomes “1912/12/30”, “S1/12/30” becomes “1926/12/30”, and “H1/12/30” becomes “1989/12/30”
 
 •
Using a “+” as the date separator: Enter the date in the format Y+M+D. When you use the “+” separator, FileMaker interprets the year according to the Year Input table below. Only 1- and 2-digit years are interpreted as Emperor years; 3- and 4-digit years are treated as Western years. For example, “2+1+2” is converted to and saved internally as “1990/01/02” (2nd year of Heisei, January 2nd).
