At MSDN Whidbeyâs class library you read: "The JalaaliCalendar class represents the
Jalaali calendar. The Jalaali calendar is also known as the Persian calendar,
or the solar Hijri calendar as opposed to the Arabic lunar Hijri calendar. The Jalaali calendar is used in most
countries where Farsi is spoken, although some regions use different month
names. The Jalaali calendar is the official calendar of Iran and Afghanistan,
and is one of the alternative calendars in regions such as Kurdish Mesopotamia,
Kazakhstan, and Tajikistan. Dates in the Jalaali calendar start
from the year of the Hijra, which corresponds to 622 C.E. and is the year when
Mohammed migrated from Mecca to Medina. For example, the date March 21, 2002
C.E. corresponds to the first day of the month of Farvardeen in the year 1381
A.H. The Jalaali calendar is based on a
solar year and is approximately 365 days long. A year cycles through four
seasons, and a new year begins when the sun appears to cross the equator from
the southern hemisphere to the northern hemisphere as viewed from the center of
the Earth. The new year marks the first day of the month of Farvardeen, which
in the northern hemisphere is the first day of spring. Each of the first six months in the
Jalaali calendar has 31 days, each of the next five months has 30 days, and the
last month has 29 days in a common year and 30 days in a leap year. A leap year
is a year that, when divided by 33, has a remainder of 1, 5, 9, 13, 17, 22, 26,
or 30. For example, the year 1370 is a leap year because dividing it by 33
yields a remainder of 17. There are approximately 8 leap years in every 33 year
cycle." Even though it gives a rather good briefing of the
calendar, however some parts really need to be changed. Besides the name of the
calendar that is still under debate, it seems to me that we have to start over
discussing about the name of the language as well. Where do they speak Farsi?!
I speak Persian. Another fault there is the era indication of "A.H".
A.H. refers to Anno Hijae which marks a Hijri date. For Jalali (if named so) it
would be A.P. which stands for Anno Persico or Anno Pesarum. If you see any other points that need mentioning, please
let me know. I am listing these points to make a feedback to MS. In the
meantime you can make your own comments to MS through the email address at the
bottom of the page linked above. Thanks, Omid K. Rad |
