Fran1,000,000,000 minutes ago would be around the year 108.
How to work it out:
1,000,000,000 minutes / 60 = 16,666,667 hours
16,666,667 hours / 24 = 694,444 days
694,444 days / 365 = 1,902 years
2010 - 1901 = 108
* note this is a rough working out, not exact figures, all numbers have been rounded, and leap years haven't been taken account.

How many years ago is 1 billion seconds ago?
There are 60 seconds in a minute and sixty minutes in an hour, so each hour is 3600 seconds. Multiply 24 to get days, and then 365.25 to get years, accounting for leap years. This is 31,557,600 seconds per year. Divide 1,000,000,000 seconds by 31,557,600 seconds per year, and you get 31 years, 251 days, 7 hours, 46 minutes and 40 seconds. (Why didn't I figure out the months? Because the months aren't equal!)
How many years ago was 1642?
To calculate how many years ago 1642 was from the current year, you would subtract 1642 from the current year. For example, if the current year is 2022, the calculation would be 2022 - 1642 = 380 years ago. Therefore, 1642 was 380 years ago from the current year.
How many years ago is 2.8 Gyr?
1 Gyr is 1 billion years, so 2.8 Gyr is 2.8 billion years ago.
What year was 43 years ago?
It is 2011 now :')And 45 years ago it would have been 1966
If 12'o clock midnight equals 4.6 billion years ago and 1 hour equals 1 billion years how many years is 3 hours and 6 hours?
3 hours = 3 hours PAST 12 o'clock = (3 x 1 billion) - 4.6 billion = 3 billion - 4.6 billion = -1.6 billion years = 1.6 billion years ago6 hours = 6 hours PAST 12 o'clock = -1.6 billion years + (3 x 1 billion) = -1.6 billion + 3 billion = 1.4 billion years ago
