Cosmic Calendar. Your lifetime is 0.15 seconds in length.

The idea of the Cosmic Calendar is old but I only happen to come upon it yesterday.

It was invented by Carl Sagan in the 70s.

In short if you put the beginning of time to now in one calendar year the last 500 years would be the LAST second of December... so December 31st 23h59:59 to 00h00.

And one individual lifetime is about 0.15 seconds.
