What is the smallest second?
Scientists have measured the shortest unit of time ever: the time it takes a light particle to cross a hydrogen molecule. That time, for the record, is 247 zeptoseconds. A zeptosecond is a trillionth of a billionth of a second, or a decimal point followed by 20 zeroes and a 1.
How long is a billion seconds?
Specifically, one billion seconds is 31.69 years or a little more than 11,574 days.

Why do Weeks start on Sunday?
The first day of the week (for many), Sunday has been set aside as the “day of the sun” since ancient Egyptian times in honor of the sun-god, beginning with Ra. The Egyptians passed their idea of a 7-day week onto the Romans, who also started their week with the Sun’s day, dies solis.
How long is a month?
Numerical relations. The mean month-length in the Gregorian calendar is 30.436875 days.
How fast is a microsecond?
A microsecond is an SI unit of time equal to one millionth (0.000001 or 10−6 or 1⁄1,000,000) of a second. Its symbol is μs, sometimes simplified to us when Unicode is not available. A microsecond is equal to 1000 nanoseconds or 1⁄1,000 of a millisecond.
How much is a yoctosecond?
A yoctosecond (ys) is a septillionth of a second or 10–24 s*. Yocto comes from the Latin/Greek word octo/οκτώ, meaning “eight”, because it is equal to 1000−8. Yocto is the smallest official SI prefix. A yoctosecond is the shortest lifetime measured, so far.
What is a shake in time?
A shake is an informal metric unit of time equal to 10 nanoseconds, or 10−8 seconds. It has applications in nuclear physics, helping to conveniently express the timing of various events in a nuclear reaction, especially neutron reactions.
