BG 9.7, Purport:

Brahmā lives for one hundred years, and his one day is calculated at 4,300,000,000 of our earthly years. His night is of the same duration. His month consists of thirty such days and nights, and his year of twelve months. After one hundred such years, when Brahmā dies, the devastation or annihilation takes place; this means that the energy manifested by the Supreme Lord is again wound up in Himself.
