When did the Vikrama Era begin?

57 BC

The correct answer is Option 3- 57 BC

The Vikrama Era began in 57 BC. It is a traditional Hindu calendar that is still used in India and Nepal today.

The Vikrama Era is named after King Vikramaditya, who is said to have defeated the Saka rulers in 57 BC. However, there is some debate among scholars about whether Vikramaditya was a real historical figure or a legendary king.

The Vikrama Era is a luni-solar calendar, which means that it is based on both the cycles of the moon and the sun. The calendar has 12 months, each of which has 29 or 30 days. The months are named after the zodiac signs.

The Vikrama Era is used to celebrate many Hindu festivals, including Diwali, Holi, and Navratri. It is also used to calculate auspicious dates for weddings and other important events.
