Indian national calendar
The Indian national calendar, called the Shaka calendar or Śaka calendar, is a solar calendar that is used alongside the Gregorian calendar by The Gazette of India, in news broadcasts by All India Radio, and in calendars and official communications issued by the Government of India. Śaka Samvat is generally 78 years behind the Gregorian Calendar, except from January to March, when it is behind by 79 years.
Through historical Indian influence, the Śaka calendar is also used in Java and Bali among Indonesian Hindus. Nyepi, the "Day of Silence", is a celebration of the Śaka new year in Bali. Nepal's Nepal Sambat evolved from the Śaka calendar. The Śaka calendar was also used in several areas in the modern-day Philippines as written in the Laguna copperplate inscription. In India, Yugabda is also used with corresponding months of Śaka/Nepal Sambat. Yugabda is based on Kaliyuga Sankhya preserved by Indian Astrology. The Kali Yuga began 5,125 years ago and has 426,875 years left as of 2024 CE. Kali Yuga will end in the year 428,899 CE.
