Hello again
Unfortunately, this problem has not been fixed in the new updates!
The Jalali calendar is widely used in the Middle East region, but the "calendar display module" does not support it and displays dates based on the Gregorian calendar!
To check this issue, you need to add the Persian language to Joomla and set it as the default language, then display the calendar module in this language.
I have attached the official and verified PHP code file for converting the Gregorian calendar to Jalali.
But I don't know how to add this code to the source of calendar display module to solve this problem!
I request you, if it is possible, add this code in the source of the icagenda calendar in new updates, so that whenever the Persian language is selected, this calendar will be executed automatically.
Thank you

Hello,

You didn't provided an online link, which could have help me ;-)

Note: Joomla includes already a Jalali php script which is supposed already to be used by iCagenda (it was working by the past, and i've not changed this part since a long time, so i wonder why it does not work anymore...)

Best regards,
Cyril

For parsing the date string, I simply use the default calendar to get the date values (year, month, day, etc.)I then use this library here to convert the Persian date values to the Gregorian date values.My code now looks like this:

string persianDate = "1390/02/07";
CultureInfo persianCulture = new CultureInfo("fa-IR");
DateTime persianDateTime = DateTime.ParseExact(persianDate, "yyyy/MM/dd", persianCulture);    // this parses the date as if it were Gregorian

JalaliCalendar jc = new JalaliCalendar();
// convert the Persian calendar date to Gregorian
DateTime gregorianDateTime = jc.ToDateTime(persianDateTime.Year, persianDateTime.Month, persianDateTime.Day, persianDateTime.Hour, persianDateTime.Minute, persianDateTime.Second, persianDateTime.Millisecond);

Of course, I'll have to take care of date components with names (months, days of the week) myself, but I can deal with that pretty easily.
