The Vikram Samvat calendar (also called Bikram Sambat in Nepali) should not be confused with the Nepal Sambat , a much more recent innovation.

It was widely believed that the era was begun by Azes's successors by simply continuing the counting of his regnal years. However, Prof. Harry Falk has recently presented an inscription at several conferences which dates to Azes's reign, and suggests that the era may have been begun by Azes himself. Most popular historians date
432-622: The era beginning in 57 BCE with Vikramaditya is not found in any source before the 9th century CE; earlier sources call the era "Kṛṭa" (343 and 371 CE), "Kritaa" (404), "the era of the Malava tribe " (424), or simply "Samvat". The earliest known inscription which calls the era "Vikrama" is from 842. This inscription, from the Chauhana ruler Chandamahasena, was found at Dholpur and is dated "Vikrama Samvat 898, Vaishakha Shukla 2, Chanda" (20 April 842).

The International Alphabet of Sanskrit Transliteration (IAST) is not a standard (as no specification exists for it) but a convention developed in Europe for the transliteration of Sanskrit rather than the transcription of Brahmic scripts. As a notable difference, both international standards, ISO 15919 and UNRSGN transliterate anusvara as ṁ , while ALA-LC and IAST use ṃ for it. However, ISO 15919 provides guidance towards disambiguating between various anusvara situations (such as labial versus dental nasalizations), which
