About the Hindu Calendar System

Calendar Overview

The Hindu calendar is a lunisolar system that combines lunar months with solar year adjustments. The Vikram Samvat era began in 57 BCE, named after King Vikramaditya.

  • Lunar Month: 29.53 days average
  • Solar Year: 365.25 days
  • Adjustment: Adhik Masa every ~2.7 years

Adhik Masa (Leap Month)

Since 12 lunar months are shorter than a solar year, an extra month (Adhik Masa) is added periodically to keep the calendar aligned with seasons.
