Lunar Month support in Intl.DateTimeFormat()

[xkeshav]

I want to support indian calendar which follow lunar months ;
currently it does not support and having no option.

what I am using currently

// Use Intl to get the current Gregorian date in Hindi
const indian = {
  weekday: 'long',
  year: 'numeric',
  month: 'long',
  day: '2-digit',
  calendar: 'indian',  // Indian calendar (though it doesn't give lunar tithi)
  timeZone: 'Asia/Kolkata',
  numberingSystem: 'deva',  // Devanagari numerals
};

const currentDate = new Intl.DateTimeFormat("hi-IN", indian);

but it return date as 16 while in Lunar Month there are 15 days only and there are 2 seprate Paksha name as Shuka and Krishna
for more information you can refer hindu calendar wiki page

so my proposal is can we have the support of Lunar calendar?
