Vaiṣṇava Calendar
This Vaiṣṇava calendar is unconventional, as it has a unique purpose - to honour the appearance and disappearance tithīs of the associates of Śrīla Prabhupāda Bhaktisiddhānta Sarasvatī Gosvāmī Ṭhākura, besides other important tithīs. Unlike other Vaiṣṇava calendars, it does not provide details of date and time of tithīs. Hence it is applicable universally, not to any particular year or location.
For date and time details, devotees may refer to their usual Vaiṣṇava Calendar. Eg. Pure Bhakti Vaiṣṇava Calendar
