Age in Hindu Vikram Samvat

Lunisolar Architecture & The Tithi System

The Vikram Samvat is an ancient and widely observed Hindu lunisolar calendar that synchronizes lunar phases with sidereal solar years. Its historical epoch begins in 57 BCE, established to commemorate the legendary victory of King Vikramaditya of Ujjain over invading Shaka forces. The calendar's year consists of 12 lunar months (Chandra Maas), with each month divided into two distinct fortnights of 15 lunar days (tithis): Shukla Paksha (the waxing bright fortnight) and Krishna Paksha (the waning dark fortnight). A lunar year spans approximately 354 days. To correct the annual discrepancy of roughly 11 days with the solar cycle, an intercalary leap month known as Adhik Maas (or Purushottam Maas) is inserted approximately every 32.5 to 33 months (roughly every 2.7 years).

Sacred Rhythms, Purushottam Maas & Cultural Governance

Historically functioning as the official national calendar of Nepal and deeply woven into religious and cultural life across northern, western, and central India, the Vikram Samvat establishes the precise astrological timing (Panchang) for major Hindu festivals. It determines the sacred dates of Diwali (Deepavali), Holi, Navratri, Maha Shivratri, and Raksha Bandhan. The intercalary Adhik Maas holds profound spiritual significance: according to tradition, Lord Vishnu claimed this month as Purushottam Maas, dedicating it to intense spiritual reflection, charity (daan), mantra chanting, and sacred pilgrimages, during which standard worldly rites are paused in favor of devotion.

Gregorian Divergence & Seasonal Harmony

Because Adhik Maas is triggered astronomically whenever a lunar month elapses without a Surya Sankranti (the transit of the Sun from one zodiac constellation / Rashi to another), the Vikram Samvat never drifts through the seasons. Major festivals remain firmly anchored to their agricultural and seasonal windows, such as Holi in early spring and Diwali in mid-autumn. The Vikram Samvat year count is 56 or 57 years ahead of the Gregorian calendar (calculated by adding 57 years after the spring new year in Chaitra). An individual's age in the Vikram Samvat closely parallels their Gregorian age, though their lunar birth tithi shifts annually within a monthly Gregorian window.
