I want to create jalaali calendar (persian calendar) instead of magento
core calendar for admin and front pages .

for this purpose I've added these lines to my requirejs-config in my module :

 'map': 
 '*': 
 'mage/calendar' : 'MyNamespace_MyModule/js/persian_calendar',
 'Magento_Ui/js/form/element/date' : 'MyNamespace_MyModule/js/form/element/date_form'

 
 

persian date and gregorian date are completely different and they have different years , months and days name . I want to show persian date to user but save date as gregorian format to database .

for sending gregorian date to server I changed onShiftedValueChange
function , I do this in my custom date_form :

onShiftedValueChange: function (shiftedValue) 
 var value,
 formattedValue,
 formattedValueUTC,
 momentValue;

 // this is very simple code that check if selected date is gregorian date or persian date 
 var englishYears = ["2018", "2019", "2020", "2021", "2022", "2023", "2024", "2025", "2026",
 "2027", "2028", "2029", "2030", "۲۰۱۸", "۲۰۱۹", "۲۰۲۰", "۲۰۲۱", "۲۰۲۲", "۲۰۲۳", "۲۰۲۴",
 "۲۰۲۵", "۲۰۲۶", "۲۰۲۷", "۲۰۲۸", "۲۰۲۹", "۲۰۳۰"];
 var englishDate = false;
 for (var i = 0; i < 26; i++) 
 if (shiftedValue.indexOf(englishYears[i]) > -1) 
 englishDate = true;
 break;
 
 

 if (shiftedValue) 

 // if selected date was persian,I converted it to equivalent gregorian format, for converting dates I used https://github.com/jalaali/moment-jalaali library 
 if (!englishDate) 
 shiftedValue = jMoment.from(shiftedValue, 'fa', 'DD/MM/YYYY HH:mm').format(this.pickerDateTimeFormat);
 

 // the rest codes are for magento itself
 momentValue = moment(shiftedValue, this.pickerDateTimeFormat);
 if (this.options.showsTime) 
 formattedValue = moment(momentValue).format(this.timezoneFormat);
 formattedValueUTC = moment.tz(formattedValue, this.storeTimeZone).tz('UTC');
 value = this.outputDateTimeToISO ?
 formattedValueUTC.toISOString() :
 formattedValueUTC.format(this.outputDateTimeFormat);
 else 
 value = momentValue.format(this.outputDateFormat);
 
 else 
 value = '';
 

 if (value !== this.value()) 
 this.value(value);
 
 

by these code equivalent gregorian date was sent to server correctly , but
when I checking the value stored in database it's completely different and invalid , for example I sent this value : 4/14/2019 5:30 am , but magento convert it to : 0010-08-10 05:30:00 !!

I think maybe the format date in my custom date_form is different from format date in magento form php code , cause this problem , because when I changed this.outputDateTimeFormat parameter to for example : "YYYY/DD/MM HH:mm" , stored value was changed and it got valid format value ( for example : "2023-08-10 05:30:00" ) , but still it has different value from the value has sent and they aren't equivalent.

I don't know where magento check input date and change it to incorrect value .

Does anybody know where magento check date inputes and changing them ?
Or
Does anyone have a completely different idea for this purpose ?

Try this, it might work:

onShiftedValueChange: function (shiftedValue) 
 var value,
 formattedValue,
 formattedValueUTC,
 momentValue;

 // this is very simple code that check if selected date is gregorian date or persian date
 var englishYears = ["2018", "2019", "2020", "2021", "2022", "2023", "2024", "2025", "2026",
 "2027", "2028", "2029", "2030", "۲۰۱۸", "۲۰۱۹", "۲۰۲۰", "۲۰۲۱", "۲۰۲۲", "۲۰۲۳", "۲۰۲۴",
 "۲۰۲۵", "۲۰۲۶", "۲۰۲۷", "۲۰۲۸", "۲۰۲۹", "۲۰۳۰"];
 var englishDate = false;
 for (var i = 0; i < 26; i++) 
 if (shiftedValue.indexOf(englishYears[i]) > -1) 
 englishDate = true;
 break;
 
 

 if (shiftedValue) 

 // if selected date was persian,I converted it to equivalent gregorian format, for converting dates I used https://github.com/jalaali/moment-jalaali library
 if (!englishDate) 
 shiftedValueNew = jMoment.from(shiftedValue, 'fa', 'DD/MM/YYYY HH:mm').format(this.pickerDateTimeFormat);
 

 // the rest codes are for magento itself
 momentValue = moment(shiftedValueNew, this.pickerDateTimeFormat);
 if (this.options.showsTime) 
 formattedValue = moment(momentValue).format(this.timezoneFormat);
 formattedValueUTC = moment.tz(formattedValue, this.storeTimeZone).tz('UTC');
 value = this.outputDateTimeToISO ?
 formattedValueUTC.toISOString() :
 formattedValueUTC.format(this.outputDateTimeFormat);
 else 
 value = momentValue.format(this.outputDateFormat);
 
 else 
 value = '';
 

 if (value !== this.value()) 
 this.value(value);
