On Gujarati Wikipedia, I want to use Traditional Gujarati (Hindu/Indian) Calendar. This calendar is different than the translation of Gregorian calendar, it is like Chinese Traditional Calendar, or Islamic Calendar, where each date of the Gregorian calendar has its corresponding traditional date (and month, year). As the calendar is Lunisolar calendar, corresponding dates/days will change every year. For example, you can see https://gu.wikipedia.org/wiki/મુખપૃષ્ઠ/ટ્રાયલ_૨૦૧૫, where in the top box, below the wikiglobe, you will see "જૂન ૪, ૨૦૧૫" displayed today, which is derrived by using '[[{{#time: F j}}]], {{#time: Y}}' . I want "જેઠ વદ ૨, ૨૦૭૧" displayed instead of "જૂન ૪, ૨૦૧૫". I am happy to assist in inputting values for the whole year anywhere with their corresponding Gregorian dates, if needed.
Please remember that "જૂન ૪, ૨૦૧૫" is mere translation/transliteration of "June 4, 2015", while the desired value "જેઠ વદ ૨, ૨૦૭૧" is an actual correspnding date according to the Gujarati Calendar.
