Time

Time is often referred to as  " the wheel of time" because the mundane creation manifests, remains for awhile then dissolves. After the destruction, either partial or final, creation starts all over again, like the wheel in a cyclic motion!

There are innumerable universal eggs or universes that are created and destroyed systematically by the breathing of Maha-Vishnu. His exhalation causes their creation and His inhalation, their destruction. Our particular universe exists for the duration of Brahma's life span i.e. a total of one hundred of Brahma's years. This is about 311 trillion human years. We are right now in the midpoint of Brahma's lifetime. The current day of Brahma is the first day of a new year; "today" being Brahma's fiftieth "birthday." Each year consists of 360 days and nights. One day of Brahma is subdivided into 14 manvantaras each consisting of 71 yuga cycles. We are in the 7th of the 14 manvantaras; and the 28th of the 71 yuga cycles. Each cycle consists of Satya, Treta, Dvapara and Kali. We are 5000 years into the Kali-yuga.

It is near  "noon" on Lord Brahma's fiftieth "birthday." Puranic information states that this is the first day of Brahma's fiftieth year (out of 100 yrs total).  This is the 7th manvantara out of 14, and the 28th yuga cycle out of 71. We are 5,000 years into age of Kali.  The age of the universe and Brahma is said to be 155,521,972,949,000 of our earth's years.
