Question:
Why is an auto calendar available through the year 2099
Answer:
The SII’s RTC denotes the year using its last two digits. These digits are then divided by four, and if
they are divisible the year is determined to be a leap year (the auto calendar determines both 1996 and
2000 to be leap years). The actual calendar, however, does not treat a year with “00” as its last two
digits as a leap year (except for the year 2000; see the following). Accordingly, although 2100 is not a
leap year, the RTC treats it as one. Therefore, this auto calendar is available through 2099.
(Note) A year is defined as a leap year when its last two digits are “00” and its first two digits are
divisible by four.
