Are you serious? A large fraction of the world's population uses other
calendars. From the Wikipedia entry "Calendar":
While the Gregorian calendar is widely used in Israel's business and
day-to-day affairs, the Hebrew calendar, used by Jews worldwide for
religious and cultural affairs, also influences civil matters in
Israel (such as national holidays) and can be used there for
business dealings (such as for the dating of checks).
The Persian calendar is used in Iran and Afghanistan. The Islamic
calendar is used by most non-Persian Muslims worldwide. The
Chinese,Hebrew, Hindu, and Julian calendars are widely used for
religious and/or social purposes. The Ethiopian calendar or Ethiopic
calendar is the principal calendar used in Ethiopia and Eritrea. In
Thailand, where the Thai solar calendar is used, the months and days
have adopted the western standard, although the years are still
based on the traditional Buddhist calendar.
Even where there is a commonly used calendar such as the Gregorian
calendar, alternate calendars may also be used, such as a fiscal
calendar or the astronomical year numbering system[1].
Add that up and it's probably over 75% of the world's population using
other calendars, at least for non-business purposes.
Hardcoding the Gregorian calendar is a serious internationalization
problem, just like hardcoding the Roman alphabet or left-to-right text
layout or octagonal red stop-sign icons.
