Age of Lord Brahma

Brahma is one of the gods of the Hindu trinity. He is the oldest amongst his siblings, Lord Vishnu and Lord Shiva. It is an accepted fact in Hinduism that Lord Brahma has a limited life span of 100 years. However, one year of Brahma is made up of a very lengthy period. The calculation is given below.

What is the Age of Lord Brahma (ब्रह्मा)

Brahma's age is of 100 years (Divine years) duration.

To understand Age of Brahma one needs to know what is Chaturyuga and the duration of Chaturyuga.

What is a Chaturyuga

One Chaturyuga = 4 yugas (Satyuga, Tretayuga, Dwaparyuga, Kaliyuga)

• Duration of Satyuga = 17,28,000 (seventeen lakh twenty eight thousand years)
• Duration of Tretayuga = 12,96,000 (twelve lakh ninety six thousand years)
• Duration of Dwaparyuga = 8,64,000 (eight lakh sixty four thousand years)
• Duration of Kaliyuga = 4,32,000 (four lakh thirty two thousand years)

Total Duration of Chaturyga = 43,20,000 (forty three lakh twenty thousand years or 4 million 320 thousand years)

Calculation of a "Divine year" or Brahma's year

• Full day of Brahma = One day + One night
• One day of Brahma = 1000 (one thousand) chaturyugas 
• One night of Brahma = 1000 (one thousand) chaturyugas.
• Therefore one full day of Brahma is made of 2000 chaturyugas.

1000 Chaturyugas = 1000 x 43,20,000 = 4320000000 earth years (4 arab 32 crore years or 4 billion 320 million years). (for ease of calculation it is taken as 1000 chaturyug whereas in reality one day of Brahma is of 1008 chaturyuga)

One day of Brahma is also called 'Kalp'

One Month of Brahma is of 30 days and 1 year is of 12 months. Total days in one year of Brahma is 360.

One year of Brahma or "One Divine Year" = 2000 (chaturyuga) x 30 (days) x 12 (months) = 7,20,000 chaturyugas = 3110400000000 earth years (31 kharab 10 arab 40 crore years, or 3 trillion 110 billion 400 million earth years)

Age of Brahma

Brahma's Age = 100 "Divine years" = 100 x 7,20,000 chaturyugas = 7,20,00,000 chaturyugas = 311,040,000,000,000 earth years. This translates to the following.

• 31 neel 10 kharab 40 arab years (age of Brahma according to Indian numbering system)
• 311 trillion 40 billion earth years (English numbering system)

The duration of age of Brahma is also called 'Maha Kalp'

Age of Lord Vishnu is 7 times the age of Brahma = 700 Divine Years.

Age of Lord Shiva is 7 times the age of Lord Vishnu = 4900 Divine Years.
