- The second issue is due to the fact that the year 2000 is a
special-case leap year. This type of leap
year occurs only once every 400 years and is an exception to the
usual rule for determining leap years. Some computer hardware and
software may not understand that the year 2000 includes the extra
day of February 29, 2000.
- The third issue is due to an older programming practice of
using dates to indicate special meanings or customized functions
within software programs. (For example, in some programs, a
special meaning was often assigned to the date 9/9/99.) It is
generally older software programs found on legacy computer systems
that have this problem. Programs created for personal computers
are less likely to be affected by this type of year 2000 issue.
The year 2000 issue, then, is really a collection of different
types of date handling issues that can affect computer systems,
including personal computers, when the new century arrives.
