someone please help ?

 

Here are some notes on IndexOutOfRangeException and ArgumentOutOfRangeException:

This sounds related to localization so you can probably focus your investigations there if you localized your app.

If you did not localize your app, then to help gain more insight into your problem, I recommend liberally sprinkling Debug.Log() statements through your code to display information in realtime.

Doing this should help you answer these types of questions:

- is this code even running? which parts are running? how often does it run? what order does it run in?
- what are the values of the variables involved? Are they initialized? Are the values reasonable?

Knowing this information will help you reason about the behavior you are seeing.

You can also put in Debug.Break() to pause the Editor when certain interesting pieces of code run, and then study the scene

You could also just display various important quantities in UI Text elements to watch them change as you play the game.

If you are running a mobile device you can also view the console output. Google for how on your particular mobile target.

Here's an example of putting in a laser-focused Debug.Log() and how that can save you a TON of time wallowing around speculating what might be going wrong:

i've got same reports after update projects to Unity 2020.3.9f1 on both platforms ios and android!
i can't reproduce this on my devices.

this is report from firebase crashlytics:

Code (CSharp):

1. Non-fatal Exception: java.lang.Exception: ArgumentOutOfRangeException : Not a valid calendar for the given culture.
2. Parameter name: value
3.        at System.Globalization.DateTimeFormatInfo.set_Calendar(System.Globalization.DateTimeFormatInfo)
4.        at System.Globalization.CultureInfo.get_DateTimeFormat(System.Globalization.CultureInfo)
5.        at System.Globalization.CultureInfo.GetFormat(System.Globalization.CultureInfo)
6.        at System.Globalization.DateTimeFormatInfo.get_CurrentInfo(System.Globalization.DateTimeFormatInfo)
7.        at System.DateTime.ToString(System.DateTime)

example usage causing the problem:
DateTime.Now.AddMinutes(60).ToShortString()

reports point to any calls datetime.tostring in any variations

 

Are you by chance using ToString on a DateTime object with a format string? It's possible the format string you are providing isn't valid for the current context, as some cultures have different calendars.

To verify, change your device language to Saudi Arabian Arabic and try running the application, as their dates are formatted differently.

You can either choose a format that works with all cultures, or pass a second argument of IFormatProvider to the ToString call provided by the InvariantCulture if you want dates to always be printed the same way, regardless of device language region.

 

This problems came on 2020 version of Unity.
same code worked perfect on 2018.4.3.

After upgrading my project, i got ~10k non fatal errors on firebase with this issue

 

Solution.
Just add this somewhere, You don't need to call this function. It will work on compilation and calendars will be added automatically

public void AddCallendars()
{
new System.Globalization.GregorianCalendar();
new System.Globalization.PersianCalendar();
new System.Globalization.UmAlQuraCalendar();
new System.Globalization.ThaiBuddhistCalendar();
}

 

It doesn't work

 

Solution works for me: add link.xml file like this to Assets folder

<linker>
<assembly fullname="mscorlib">
<namespace fullname="System.Globalization" preserve="all"/>
</assembly>
<assembly fullname="System.Globalization.*Calendar" preserve="all"/>
</linker>

After a few days of research, I found it somewhere on the forums. Now this solution works and crash reports are no longer received.
As far as I understand, this happens because there is a strip of unnecessary code by the compiler

 

If you're just calculating timespan then I think you can try using DateTime.UtcNow instead of DateTime.Now.

 

This worked for me thanks a ton, used invariant culture as a format in ToString

 

Worked perfectly for me. Solution with AddCalendars() did nothing. Solution with XML file crashed builds and only this one really fixed the problem.

 

Unity 2020.3.34f1 / IL2CPP / .NET4.x
Made project on Windows and released on Android.
Have the same issue.

Code (CSharp):

1. Non-fatal Exception: java.lang.Exception: ArgumentOutOfRangeException : Not a valid calendar for the given culture.
2. Parameter name: value
3.        at System.Globalization.DateTimeFormatInfo.set_Calendar(System.Globalization.DateTimeFormatInfo)
4.        at System.DateTimeFormat.ExpandPredefinedFormat(System.DateTimeFormat)
5.        at System.DateTimeFormat.Format(System.DateTimeFormat)

I'm using DateTime.Now and there is no possibility to use UtcNow.
BTW issue appeared after I switched to unity 2020. Unity 2019 hasn't such issue. Also it appears on only on devices with special calendar systems. For ex.: Thai

 

reimport all assets and try switching to some other platform and back to your targeted platform, this worked for me.I do this every time I switch the editor version

 

This Method works for me!

 

It took me some time to find a bug. Thanks @Archi_16, you pushed me to correct direction. I was trying to get a name of the month but I was creating date new DateTime(1, monthIndex, 1) which of course is outside of the range for UmAlQuraCalendar which is 1900-2077. Instead I had to use current year: new DateTime(DateTime.Now.Year, monthIndex, 1) If someone is facing the same issue, make sure to double check that all manually created dates are not going outside of range. BTW ThaiBuddhistCalendar seems to be working fine, even though current Thai years is 2565.
