The general
form of a Japanese date is
eyymmdd:
is the first letter
of the name of the imperial era(Meiji, Taisho, Showa, or Heisei).
is an integer that
represents the year.
is an integer from
01 through 12 that represents the month.
is an integer from
01 through 31 that represents the day of the month.
The
e value
can be separated from the integers by a period. If you omit
e, SAS uses the current imperial era. You can
separate the year, month, and day values by blanks or any nonnumeric
character. However; if delimiters are used, place them between all
the values. If you omit delimiters, be sure to use a leading zero
for days or months that are values less than 10.
