Dates & calendars

[eschneider]

Hello,

The minimum supported year acording to the HebrewCalendar is 5343

Then why do I get the following error when performing the following?:

new DateTime(5343,1,1,New HebrewCalendar)

System.ArgumentOutOfRangeException occurred
Message="Specified time is not supported in this calendar. It should be
between 01/01/1583 00:00:00 (Gregorian date) and 09/29/2239 23:59:59
(Gregorian date), inclusive. Parameter name: time"

new DateTime(5343,1,1,New HebrewCalendar)

Because the minimum *date* in the Hebrew calendar supported by .NET is
5343-04-07. Anything before that goes before 1583-01-01 (Gregorian) and is
therefore not supported.

Thank you very much, Jeroen, for your post.

Hello eschneider,

Thank you for using Microsoft Newsgroup Support service. My name is
Lingzhi Sun [MSFT]. I am very glad to work with you on this thread.

The HebrewCalendar class in .NET Framework only supports the date between
01/01/1583 00:00:00 (Gregorian Date) and 09/29/2239 23:59:59 (Gregorian
Date). We can retrieve these values by calling
HebrewCalendar.MinSupportedDateTime and
HebrewCalendar.MaxSupportedDateTime. For detail, please see
http://msdn.microsoft.com/en-us/library/system.globalization.hebrewcalendar_
members.aspx.

To convert these Gregorian Date to Hebrew Calendar, you can refer to this
tool:

d=12&hm=Nisan&hy=5769.

Gregorian Date ------ Hebrew Calendar
1583/01/01 5343/04(Tevet)/07
2239/09/29 5999/13(Elul)/29

If you have any other questions, please be free to let me know.

Thanks, Guys

I did not realize it was the month and day, seems strange not to support the
full year of 5343.

Also I think the error message sucks. It should show the valid Hebrew dates
not Gregorian.
Likewise the debugger always shows the dates as Gregorian, making any
trouble shooting a pain.

Thanks,
Eric

Hi Eric,

Thank you very much for your feedback.

The HebrewCalendar in .NET Framework supports the Gregorian Date from
1583/01/01 to 2239/09/29. So it only supports the corresponding date in
Hebrew Calendar from 5343/04/07 to 5999/13/09. I think that is why the
HebrewCalendar class cannot support the whole year of 5343 in Hebrew
Calendar.

For the error message, I think your request is quite reasonable. It is my
pleasure to help send a wish to our product designers via internal channel.

They always ignore me...

Here is the reply:
Thank you for sneinding your suggestion for improving the behavior of the
calendar classes provided by the Microsoft .NET framework. This particular
scenario is considered as by design because the exception message uses the
invariant culture to show the error message. Accordingly, what you are
seeing is the expected behavior for this class. Thanks again for reporting
this suggestion and we hope that you enjoy all the globalization functions
in the framework.

My reply:
Well , my argument is that it is a crappy design. But this is exactly the
reply I expected. Every response I get from MS is this is by design. That
does not mean it is correct!
