What is wrong with the Vaishnava calendar? different nations have different calendars the popular Gregorian calendar also Islamic everything is going to the point that in the USA and Germany monotheists will call themselves deists because religiosity is at a minimum it is necessary to make a calendar that would suit everyone like the French calendar
the world has become globalized it is necessary to create a common international calendar soon 55% of humanity will become deists, not monotheists
