Can there be a fixed Vaishnava calendar, where all the holidays/special events are the same date each year? Isn't the significance in celebrating the event? Getting the day exactly perfect isn't that important, is it? Is a fixed calendar possible?

i think that this vedic dates an commemorials are precented variably.. maybe EKadasiS are named the same each year, but for example... Prabhupäd celebrates his birthday on tuned dates, and in our calender it came to be at diferent days each yr !

nature is versatil !

They are fixed, that is on the vedic calender. And as it is important have for example ekadasi on the exact dates as they were prescribed by Krishna, they shall stay fixed on the Vedic calender, not on ours.
