universe is 13.7 billion? years old- how many seconds?

Simply take the number of years multiplied by the number days in a year by the hours in a day by the minutes in an hour by the seconds in a minute

13.7 billion years x 365.25days/year x24hours/day x 60minute/hour x 60seconds/minute

Years, days, hours, minutes, all cancel each other out in the equation to leave you with seconds.

The Universe doesn't have days.

You are being anthropomorphic.

Let me calculate them on my deification tables.

plus or minus 0.2 billion years in seconds.
